Joe effect

Relatively simple effect. Barber shop rainbow pole is the basic effect, and then there are rings that come down when a ray is detected. There are a few simple variables that were hard to tweak since luma doesn't seem to be implemented yet and without seeing the true scale of the thing. These configuration variables are spelled out pretty clearly right at the top of my effect if you feel the desire to tweak them. Hopefully will work nicely as is though!

FYI I'll be away from computer from now till I get back to Boston, and a fair chance I'll be completely out of contact starting around midday on Sunday.

Wooooooo.... see you out in the dust!
