Well, I'm still noodling about with Flying Meat's Acorn image editing toy with my Mac's iSight Camera. I'm getting a grip on the palette of filters and controls. I might actually know how to do something on purpose in the next few days, but I think that I'll take a break to do some writing. Hopefully my fingers, eyes and what constitutes my still existing cerebrum will retain what I've learned in this digital finger painting. Anyhow, I recommend Acorn to anybody who doesn't always need the full features of PhotoShop, and will be happy for a lightweight and easy to learn editor.
