Nerbacular Drop

Yo!

I was watching a recent Valve video concerning their upcoming game Portal, and Doug Lombardi mentioned that the idea originally came from a game design institute in Washington, where a group of students had created a game called Nerbacular Drop.

This game is free, available here: http://www.nuclearmonkeysoftware.com/narbaculardrop.html

Apparently the Valve guys invited the students onboard to make their "next thing", namely Portal, using the Source tech.
