An experiment using an educational multiplayer web game

Here's a blurb I found describing an educational game that is actually being used as an experiment in educational psychology. It may be something along the lines of geosense.net. You have to create a login and wait for someone to play. No one was there when I looked at it, but it sounded interesting.

Develop Problem-Solving and Creative-Thinking Skills
Created in the Department of Computer Science at Brandeis University, PatternBEE.org is an educational multiplayer environment where two players challenge each other with geometric puzzles using a rare version of Tangrams. The game is fun and challenging and builds skills in geometry, spatial rotation, problem solving and creativity. Also check out SpellBee and MoneyBee and, coming soon, GeograBee and CalcuBee.

Here's the site.
