New Puck.js production run

Light mixing: right now I'm using some special high-efficiency LEDs…

@Gordon: Can I ask which LEDs you're using? (Or what their levels of efficiency are?) I love hunting down components.

Also I'd found that putting a little blob of something like hot glue over the LEDs diffuses and mixes everything a lot

I thought about that. Now I'll def try that with one of my Pucks!
