After getting a bunch of pictures of deathtraps at events, figuring that such events should be blogged about in a deathtrap-centric location, and deciding that the retro-static-HTML site was going to be too much hassle to do all that with, I've gone and put together a new website, and filled in some back-entries for events that have already taken place. There are still photo galleries to be set up, and a mailing list widget to be bolted in, but at this point, it's certainly no worse than the old site (and unlikely to be brought to its knees by any future work), so here it is.
Any videos of this? I don't quite understand what it is. You hold on to the ropes and roll around?
It's pretty open-ended what you can do with it; some of them have ropes set up in them that you can use for climbing, rolling, holding yourself in place while other people roll it, etc. Some are left bare so that they can be climbed on in ways that take advantage of the ability to roll them. I've made a hammock for installation in one of them (and it's still usable while the deathtrap gets rolled..)
It's kinda like asking what you can do with a ball or a deck of cards; use your imagination (and if you come up with something really neat, tell people--like me--about it).
