The applet lets you manipulate the 4D objects, rotate them around, apply various rendering styles and stereoscopic viewing options, and in general have a grand old time. If you can completely understand what you are seeing, then you may be a mutant, and you will go far in the field of computer graphics.
This work is part of a long-term research agenda of mine to figure out how the brain works. I have three conflicting hypotheses:
By implementing this work as a Web-based applet, I will be able to do widely dispersed user testing to answer these questions. I'm also planning over the next year to add haptic feedback (via the PHANToM) and head-tracked stereoscopic display, go give the greatest possible sense of hand-eye coordinated immersion in a 4D play-world.
