I think this is the first time I've heard of either tool. That Etch-a-Sketch Animator is pretty awesome.. the closest thing I have tried to that is EasyToon, an art program made just for drawing black-and-white animated GIFs.
Haha, I just tried Googling it and the only other English-language thing I dug up is me talking about it with @kirkjerk 12 years ago on the Gamer's Quarter forums. I guess I was the only one who gave it a try?
@spindleyq bless candle for making tools for the unskilled at html peasantry such as myself, I'm enjoying bipsi more than bitsy due to a few quality of life features not having to depend on plugins... Flickguy and tape window are also fun
