The standard way of making travel board game sets is to use magnets. This is a daft idea, for two reasons:
  1. Magnets are heavy; for instance, I have a "travel" Go/shogi set which weighs a ridiculous 800g, only 80g less than my full-size set.
  2. For gameplay, it's rarely enough to keep the pieces on the board: you also need to keep them at the same point on the board's surface. Magnets aren't very good at this. If your board gets a knock or tilt, the pieces will slide, possibly in ways that alter the game state.
My parents have a travel Scrabble board from the pre-magnet era that doesn't suffer from these problems. The board is a stiff piece of cardboard with holes punched through at the corner of each square, and the tiles all have little protrusions at the corners that press into the holes. The whole thing is wonderfully light, and once placed, tiles stay in position very effectively - all things considered, it's much better than the magnetic travel Scrabble sets you can buy today.

[My parents were much mocked by their friends for taking said board on their honeymoon, but they had the last laugh when they were delayed for hours in Marrakesh airport on their way home. Conventional honeymoon entertainments were unavailable, but Scrabble passed the time very effectively.]

I've been thinking since about 2006 of making a Better Travel Go Board. At first I thought of using snap fasteners for the stones and their attachment points - this wouldn't save much weight over using magnets, but it would solve problem 2. Even better, you could make the board out of cloth and then fold or roll the board up half-way through a game (in case you had to get off the train before the game finished), then unroll/unfold it later to find your game position preserved. The problem would be construction - though rivet-attachment snap-fasteners exist, they're expensive, and sewing on 361 attachment points by hand does not strike me as fun.

So I put the idea on the back burner for a while, until I came up with a better idea: use velcro for the stones. Almost as resistant to lateral movement as snap-fasteners, and much lighter. Glue-on velcro spots (or "coins", as the Velcro company calls them) are available, in both black and white, and you can buy only the hooks or only the loops, so I wouldn't have to throw half of what I buy away. Brilliant! I'm not the first person to think of this, unsurprisingly, but nobody seems to be making them.

Here are my remaining problems:
  1. It's uneconomic to buy enough coins for a Go set in small packets; by the time you've done that you might as well have bought two 25m rolls (at about £23 per roll including VAT). A roll has about 1550 coins on it, which is enough for 8.6 armies (but the .6 should probably be set aside for spares).
  2. Since Go boards have an odd number of points to a side, it wouldn't fold in half neatly. Maybe it would roll up, though - I'd have to check this. While I'm buying velcro, I should probably get a velcro cable tie per board.
  3. I can't find a UK-based supplier of beige coins for the attachment points. I can think of a few possible solutions here:
    • Order them from the US, and suck up the postage costs. I'd be saving some money on the actual coins, so this might not be too bad.
    • Use hook-coins for the stones, and felt for the board. I'm not too happy with this idea: I doubt they'd stick well enough.
    • Cover the board with strips of velcro. Either six 50mm strips (foldable, but not very rollable, and points on the middle line wouldn't be very nice to stick to) or nineteen 20mm strips, for a slightly larger board. Again, I can't find any (good) UK suppliers of beige tape rolls, but I can find some on eBay by the metre - this works out at about £3 per board for the 50mm approach, or £7 per board for the 20mm approach. Oh, and it would be sew-on, so I'd need to borrow/hire a sewing machine. Bah. I'm also not sure how I'd draw the lines on the board - anyone have any experience with fabric pens and velcro?
So, I have some questions for y'all:
  1. Can you see anything wrong with my thinking above? (In particular, can you find UK suppliers for beige coins or smaller velcro rolls?)
  2. Would you be interested in going shares with me? If I can find seven other people who want to do this, the cost drops to around £9-15, with the 50mm strip approach at the bottom of that range, the 20mm strip approach at the top, and the beige coin approach in the middle. That's not counting the cost of containers for the stones; the way I see things, you can buy your own Altoids tins more easily than I can buy them for you.
tl;dr: collaborators/customers wanted for ultralight and reasonably cheap travel Go sets. Who's in?

I keep getting assaulted by daft ideas for things to make - you may remember the achiral fan1, the board games, the telescopic juggling clubs, the reimplementation of TeX in Caml... Sometimes, I get as far as starting to make them before abandoning them uncompleted, but I'd love to finish one one of these days. I blame [livejournal.com profile] dynix2.

Anyway, the last couple I've come up with are as follows:

Mathematical fridge poetry. Why write nonsensical bad poetry when you can write nonsensical mathematics? The idea is to get a load of mathematician's names, common terms, prefixes and suffixes, and then to mix them up and produce sentences like "Theorem: for all semi-connected Grothendieck-Riemann lexicography spaces x that are cohomotopically étale, there is a non-gauge-equivalent Erdos matroid Ξx such that ∂Ξx ≈ ∫√O(x). Proof: exercise." For bonus points, combine it with a tabloid-headline fridge poetry set :-) I reckon there could actually be a market for such a thing: Thinkgeek could probably sell a few (speaking of which, this game looks dead interesting). Of course, the magnetic poetry folks probably have a patent on the whole idea of putting words on bits of magnetic paper, but that doesn't stop me making a set for myself. I've bought a sheet of printable magnetic paper: now I just need to choose the words for it.

My first cut at the wordlist for such a thing is as follows: maths/science types (I'm particularly looking at you here, [livejournal.com profile] michiexile, [livejournal.com profile] weaselspoon, [livejournal.com profile] benparker and [livejournal.com profile] elvum), what do you think?

Maths words )

Travel Go board You know those magnetic travel games that lose their magnetism slowly and don't stop the pieces sliding into the wrong position? There is a better way, which used to be standard. Instead of using magnets, you keep the pieces on the board using pegs and holes in the board. My parents have travel chess and Scrabble sets that work on this principle. Also, I have a Go board that rolls up, which makes it much more transportable, but the stones are still a bit too bulky. I'd like to combine the two ideas, by having a (small) cloth board with the male half of a snap fastener at each intersection. The female halves (complete with white or black plastic covers) would be the pieces. I'm not sure what I'd put the pieces in when not in play, but hopefully they'd be small enough to fit in a mint/boiled sweet tin (thus getting my own back on everyone who's told me that Go stones "look like Mint Imperials").

The downside is that there are 361 intersections on a full-sized Go board, which is (a) potentially more money than I'd like to spend, (b) a lot of sewing. It turns out that you can get snap-fasteners with bendy metal teeth that can be pressed into place without sewing: I can also find eBay folks selling snap-fasteners in lots of 180 for about £3. Unfortunately, they're the sew-on kind :-(

1 Speaking of which: [livejournal.com profile] azrelle, could you please be a bit more specific about where you get your fan guards from? I've tried in a couple of art shops and had no joy.
2 I wonder what would happen if [livejournal.com profile] dynix (who among my South London friends can be and is blamed for anything) were to meet James Needham (who fulfils a similar role among my Light Entertainment friends). Possibly a gigantic scapegoat made of electricity would materialise and suck all the atoms in the Universe into itself, ushering in a new order of things. But come to think of it, why haven't they ever met? What are the odds of two people being blamable for any conceivable thing and yet never appearing in the same room at the same time????? I shall watch them closely: maybe one day [livejournal.com profile] dynix will say "What-ho", or James will let on that he's not so ignorant about computers, and then I will know their secret...

I've started playing Go again after almost a year off. It's great, but the rest has not helped the standard of my play. I've mostly been playing against Philipp, but I got a few games in at The Burn (about which I will write soon). Won three and lost one against someone I'd taught to play, won one and lost one (heavily) against a Chinese guy called Qiming. The game I won was an exhibition game, in which we explained what we were doing to the gathered audience (no, really). Getting a window on his strategic thinking (much more developed than mine) helped, but the really helpful thing was when Philipp said "But isn't this group here dead now?" Indeed it was, and that forced Qiming to choose between saving that group (and losing its corner) and saving the group that was then in contention. He saved the corner, and I went on to win the game :-)

Philipp's getting worryingly good, actually. I've already taught him everything I know about strategy, and he makes fewer stupid mistakes than me. I should probably read more of my Go book. And, you know, play more. We had one good 13x13 game on the way back from the hills on Saturday, played on a bit of paper. I had a live group containing most of the left side of the board, but I reckoned he might be able to make two eyes in that bit of territory. Hoping he'd decide not to risk it, I passed, and so did he. We counted up, I'd won, and so I said "You know, I'd have tried to make two eyes in that big wodge of territory on my left. You could probably have managed it." So we restarted the game, and he beat me by as much as I'd beaten him before :-(

Also, while I was away at The Burn, an eBay purchase arrived: inspired by this blog post and a recommendation from [livejournal.com profile] johnckirk, I'd ordered a copy of the German board game Carcassonne. Richard said that he'd played it before, so we invited him home for dinner and a couple of games. It's excellent fun, and fifteen quid very well spent. Little or no setup time, about an hour's play, good balance between luck and skill, very sociable. My only gripe is that it could do with more tiles and a longer playing time.

[Yes, I know I said I'd stop reading ESR's blog. I have at least managed to stop commenting on it. By the way, the Greg Kostikyan mentioned there is the one who invented the term grognard capture, which I blogged about a while ago. Small Internet, eh?]

While I'm talking about games, this is one of the funniest things on the Internet. What would happen if a Karate Kid-style sports movie starring Leonardo Dicaprio were made about Go?
