Cut the knot? What am I - Alexander or somebody? Hey, look - I'm not your guy. I'm just some kid from the neighborhood.

Good post, plep. I have used CTK for many math lesson plans (I am working on my CA teaching credential). It also has 41 proofs of the Pythagorean Theorem, including one by President Garfield in 1876. The Math Forum from Drexel University is another good site.
