I don't get it either. Your demo link just leads to a page with some text boxes on it. I tried it in Firefox and Safari and can't see anything that looks "noisy". I tried changing some of the parameters but that just crashed Firefox.

It wasn't github. It was the fact that, at first blush, Noisy seemed to fail the actually-does-something test.

It turned out not to be so, but it did take me a lot of control wiggling to figure out what was going on.
