If you've read many of my other posts, it's probably become obvious that I enjoy spatial reasoning.  It's fun because it involves creating images in your head and knowing how things work together.

One of my favorite childhood toys was this set called Gearopolis.  It was made by Discovery Toys, and it only seems to be available used now.  But all is not lost for fellow gear-lovers who want to play with a toy like this.  Gear Tech is a similar set (and it even includes belts to connect gears!), and it's available from Amazon.com.
