rainbow loom plugin

[person_321]

well, this time I decided to make something a little bit more advanced, so after tweaking some code from Madjik's bubble tut, I was able to come up with this

This plugin renders the loom of your choosing onto the source canvas.

(thanks to Ego Eram Reputo for helping me out with the sliders)

enjoy! (this effect is found in render)

With all due respect, a plugin that has no configurable parameters is going to be of limited use to a lot of users.

I'd highly recommend a least a couple of sliders to change the pattern and/or orientation.
