I found out about Squeak and am hooked since.
Really a cool environment.
My goal is to prototype (and maybe release) a children's software to teach them basic math that most of them are missing those days.
I am doing that with two other people: my girlfriend Catherine Absil (NLP practicioner and maths teacher) and another NLP guru, Alain Thiry, which is a published author on learning strategies.
Now able to browse the class library, create morphs and tell them what to do, playing movies, scripting the thing. It's mind boggling but results are there... that's cool.
For a living, I run my own software shop, http://www.highoctane.be
