This page lists some of the projects I started before joining Google:
The Python Challenge – An online puzzle in which each level can be solved by a bit of Python programming. During its first year, hundreds of players were playing daily. Many publicly admitted they got addicted to it. It was even mentioned on the show“Click Online” of BBC World.
Webilder Desktop – Flickr and Webshots photo manager for Linux. This small panel applet automatically downloads stunning photos and sets them as your wallpaper.
The MathNet Project – A sophisticated homework checking system, which also offers interactive lessons. The project is being used by the Department of Mathematics at the Technion for several years. The system serves thousands of students weekly.
