Random Walk in Away3D 4.0

I don't know what it is but I just love the patterns, or lack of patterns, in a random walk. Especially when it's done in 3D. It sort of reminds me of a complex protein molecule folding up on itself. At any rate it's fun and easy to play around with and so I thought I'd update my old random walk done in Away3D 3.6 with a new one done with Away3D 4.0 beta. The only real difference with this one...
