Here's the newer version: https://scratch.mit.edu/projects/1374225163/ A demonstration of Neat4D, my work in progress 4D engine, I thought a good test or showcase would be it rendering the iconic Tesseract(Or 4-Cube), use the sliders to rotate it 3 dimensionally and 4 dimensionally.
I'm planning to render a 5-Cube(Or Penteract) next! Note: POV is misleadingly named.
