Finishing touches on Helix

I'm guessing the rendering framework got some performance tweaks because helix now runs at 60fps.  These changes put some finishing touches like making it bigger and moving it a bit to cover more of the rig at once.  It also adds some color variety to be a bit more visually appealing.  It looks pretty good now.  I might play around with adding a projective transform to play around with perspective a bit, but I'll be pretty happy to see it playing on the playa as it is.
