plep-- you probably lead MeFi in total "This is good"s, and I think you've done it again. This is a great find. I've just started in on the page and already I find this, which is really cool...

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

Yes, this is good, and fun. I'm playing with the analog devices, and planning to check out much more. Thanks, plep!

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.
