The beryl cube. The wallpaper is designed by me, you can find it here (cc-by-nc-sa license + permission to use on a few personal commercial computers hereby granted).
The ugly borders between the "sheets of glass" were caused by the wallpaper being one column of pixels too small due to me not paying attention while exporting from inkscape. If you downloaded the wallpaper, you may want to have the corrected version, which can be found in the same location. Sorry!
Wow, quite awesome. Nice trick!
That is pretty cool
