ToneTester
by Suitable Systems
ToneTester is a Macintosh application that tests hearing. Specifically, it looks for offsets in how each of a person''s ears hears pitch (the formal term for this is "binaural diplacusis" or "interaural pitch difference"). To use it, you adjust a slider until your ears hear the same pitch, and then ToneTester tells you the actual pitch difference.

Gravitational Lensing
by Wouter Dhondt
Einstein's General Theory of Relativity demonstrates that a large mass can deform spacetime and bend the path of light. So, a very massive object, such as a cluster of galaxies can act as a gravitational lens. With this program, one can draw images to see the effect of gravitational lensing. You can easily test the effects of several parameters by changing them and redrawing the image.
