In my two previous companies, I've worked on drag-and-drop programming, and knew that I wanted a syntax free environment. No typing.
Turtle graphics may have been good enough for those of us raised on the limited graphics of pong and Asteroids, but it would be hardly good enough for today's children who have the attention span of gophers.
I didn't want it to be too easy. I wanted a real programming environment, that would teach them debugging skills and all the rest.
Last, it had to be fun. I should be able with a couple of short lessons, to teach them to make a movie or a game.
What did I find?
