I'm still trying to get LAIKA running on as many computers as possible. If you're having trouble, it would help a lot if you posted your configuration and experience here. Thanks!
It was down due to a Shadertoy bug--thanks for letting me know! Should be fixed now.
FYI you won't find it listed publicly on Shadertoy anymore -- it doesn't work on certain machines, and so I think the admins there would rather keep it unlisted than crash a few browsers on their homepage (and understandably so).
