The address is demo.atornblad.se/artsy, but I haven't tested it that many browsers and devices yet. I do know that it crashes on Windows Phone 7.8 after just a few scenes, but it works really nicely on my iPad 3, especially in fullscreen mode. Add a shortcut to your iPad's start screen for fullscreen mode.
I will make some changes to the bitmap tunnel effect, and make sure that the demo runs correctly on most browsers and devices. Also, stay tuned for parts 2 and 3 of Sanity Arte, and of course there will be a blow-by-blow description here on atornblad.se when the whole thing is complete.
