Visualization is neat. What I would like to see, more for debugging purposes than for learning (but I suppose it would be useful for both), is a debugger that makes it very easy to graph watched variables, function call frequencies, etc. Being able to quickly visualize data trends inside a program would be immensely useful. Maybe something like this already exists. Am I missing out? ETA: Make sure to click the "sandbox" link on the aesop academy page. There's more visualization and better controls available there. Neat stuff... I would have liked this when I was playing around in my "computer science" class in high school.
