This site has two versions, high speed and low speed. Choose low-speed since the Flashplayer that powered the high-speed version is no longer supported.
The low-speed version will show you the device and give you lots of information about the item you art looking at. Things that were really cool in this section is the Sorceress’s Mirror, UniBug, and Compound Microscope. I personally thought the information in this section was more in-depth and interesting than some in the high speed version.
Here’s a description of the UniBug:
Mark W. Tilden
English, born 1961
Twenty transistors and fifty mechanical parts
3 x 8 x 12 in.
Lent by the Los Alamos National Laboratory, Research Laboratory,

Although digital devices dominate today’s technological landscape, physicist Mark W. Tilden has built hundreds of analog devices that can mimic natural behaviors. These “BIObots,” as he calls them, have nothing to do with computers, resembling instead “the 98 percent of living species that manage fine without a brain.” According to Tilden, “Unlike digital technology, analog devices may or may not do the same thing twice because they aren’t programmed. You can influence them, but you don’t have absolute control. In cases where their survival is threatened, they have the advantage of instinct.” The Unibug 3.1 is an example of a BIObot that senses light and then moves toward the light source.”
This site is very neat, so take your time and explore all its nooks and crannies.
