Try Lambda Calculus!

Have two minutes? Give the Lambda Calculus a shot right now!

If you're a beginner you can start with some basics:

x, y, a, and other letters!
\x.x, \x.\y.x, and more!
(\x.x) \z.z, (\x.\y.x) z q, and even (\x.x x) (\y.y y)!

Hacked out in a night by Mike Burns. Thanks to Try Ruby and Try Haskell; and to jison and jquery-console. Learn more about the Lambda Calculus at Wikipedia.
