If someone didn't already have the first Portal game, it's now free if you get it from here and do so before the 20th. Valve's trying to push Portal and Portal 2 to the classrooms, it seems.
Using interactive tools like the Portal series to draw them in makes physics, math, logic, spatial reasoning, probability, and problem-solving interesting, cool, and fun which gets us one step closer to our goal—engaged, thoughtful kids!
