This first website takes you to a stone skipping robot. It was built because a lot of people want to skip stones, but they don't always live near a source of water which allows for this desire.
The next site features an ascii face, and the eyes follow your mouse around. However, if you should click on the face, and hold the mouse button down, you'll be in for a nice treat. The longer you hold it down, the better it gets.
This next website takes you to a place where people have set it up so you can see what they're doing, as well as turn their lights on and off. It's fairly interesting, the camera is controllable, and their cars also broadcast if they're on the move, so you can see what they're seeing.
And finally, one of the stranger sites I've come across lately. It features He-Man singing What's Up? on loop. That's all there is to it. I'm not really sure why it was created, but it's hard not to watch the whole thing.
