Jerome Lemelson earned more than 500 patents for all kinds of inventions in communications and medical technologies, robotics and machine vision, and other high-tech stuff.

But about one-eighth of his patents describe toys -- inflatable toys, jumping toys, toys with propellers, toys that run on tracks, target games, dolls, and more.

We've created a screensaver inspired by three of Lemelson's patents for toys and the artwork of inventor David Gittens. This colorful and engaging screensaver contains animations of the three toys and cycles through the set, changing to a different toy every two minutes.

The propeller on the toy cap rotates. Lemelson designed the cap so that the propeller could be interchanged with things like a whistle or a rotating ball, all operated by blowing through a tube, so they would work just as well indoors as outside. This was the first patent awarded to Lemelson!

The dog jumps and barks. Lemelson's toy dog would squeak when air escaped from the cocked bellows inside it.

The space age car zooms across the screen. Lemelson's propeller driven car was powered by a twisted rubber band and would race across the floor.

Download the screensaver to your computer--and have some fun playing with Jerry's toys!
