Designing homeworks

I'm teaching CG this semester, and it's a lot of fun to go back and read some of the older texts and papers. Preparata and Shamos is actually quite a neat book, chock full of useful tricks and techniques; if only they had better ways of describing their algorithms ...

The real challenge is designing good assignment problems, and I've almost given up on this. With the number of courses available on the web, and the amount of information accessible via Google, I'm hard pressed to write down a question that can't be solved using Google and a few keywords. Even the trick of digging up interesting lemmas from related papers doesn't work if you mention the paper in class. Or maybe I'm underestimating my students' potential desire to solve the problem themselves.
