I just got this from a friend, and I think it has an IT geek factor of at least 8 (scale of 1-10), not to mention it is simply some cool coding.

Click here, and follow these directions:

Place your mouse at the top of the photo. You will notice it is 6:10pm. Bring the mouse down slowly over the photo……. Night time appears, and the lights come on.
At 7:40pm, it’s dark! Photo technology at its best!

Tres cool, my friends. Tres cool.
