I've built my own js lib to help with this (https://github.com/threepointone/twain https://github.com/threepointone/twain) Couple of demos - http://threepointone.github.com/iso-gol/ http://threepointone.github.com/iso-gol/ and http://threepointone.github.com/beam/ http://threepointone.github.com/beam/ (might not work on ff19) still experimental, but I'm learning.
