Back in 1988 or so I remember coming across a toy called, if I remember right, "The Brain." It was clear plastic, cylindrical in shape (a little bigger than but similar to a stack of 20 CDs), and it had about a dozen small black rods sticking up around the top plane of the cylinder. You could see a bunch of interlocking plates in the inside of the cylinder, and they controlled which rods you could move at which time. The goal was to figure out the code. Has anyone seen this toy or know where I can find one? I've tried eBay and Froogle but no luck.

I want to cultivate some good mental exercising habits. For that, I need some good, diverse sources for puzzles and activities. Specifically, I'm looking for, preferably free, sites with a decent database of verbal, logical, spatial, lateral thinking games. The format can be flexible, so crosswords are included. Also, games that test and hone reflexes and reactions are also welcome. Additionally, ADHDers are also advised to stimulate the cerebellum. Any help on that? Basically, I'd like a list of resources for complete brain workout, that can be performed atleast once every day. Obviously, I'm not looking for one site to include all of the above.
