Program Ideas

I finished learning about pointers and pointers to arrays and wrote an overly complicated Fibonacci Buttsorter, then realised i needed to know nothing about pointers and pointers to arrays and wrote a quick hack version that took 1/4 of the lines and 1/10 of the time. Anyway, doing that I learned alot of new. important stuff about programming. So, [spoiler]/prog/[spoiler] any ideas of quick programs like this I can make that will teach me interesting/important stuff about programming? And yes, I have read SICP

Oh, I failed at BBcode.

Fine, I will finish it. But still, any ideas you guys have would be helpful

Start by finishing SICP. Then come back.

Keep an eye on programmingpraxis.com and try out some of the programs he posts.

Implement your own PostScript.
