Here is the calculator

Clicking the "Run" button compiles all of the LC code to JavaScript and runs the selected one. The "Reduce" button shows the intermediate alpha, beta, and eta reductions required to reduce an LC expression.

There is a small version of Space Invaders, written in Lambda Calculus, here: It's also available in this repository, but the image links work better from a regular web server. It's not finished, yet :)
