Mouse to spin it!
I was just tweaking and optimizing my 3D code here and as usual I stumbled upon some side-effects I wanted to share with you. It's a reference to my previous project "Red Ghost Cube" - http://scratch.mit.edu/projects/20233806/ only this time it's a filled cube. Update 1-NOV-2014: Added block to calculate back-face culling. And implemented suggestion from @s_federici to fade away the trail.
