When I load the page it's saying "Sorry! The shader you are requesting doesn't exist.". I couldn't find it by searching on shadertoy either. Is the game down?
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).
