I do like Processing, although it’s been a while since I made anything with it. It looks like Processing is getting even better, with a new user interface which they’re continuing to develop post 3.0.
This comes on the heals of Codepoems, a new IDE for Processing, which I was considering trying out. I’ve no idea of whether or not Codepoems will work with Processing 3, that’s probably the next step for me.
