live goeometry

It’s a geometry modeling tool that runs in the browser.

I think compass and ruler construction is just an amazing intersection of the practical and the ideal, mathematical proof and hand work. Here’s a list of starter constructions.

Live geometry lets you create the circles and lines you need to have in order to do a construction, then move and resize the parts while keeping them constrained in a way that maintains the construction. Look at the demos section for examples of this. The parabola is especially good.

There’s a good screencast

Reminds me a bit of phun.
