Here's today's quick snippets:

* It's here! Back on April 1st of this year, ThinkGeek.com created the 8-bit Tie as a joke. It resulted in such a large volume of e-mail that they promised to make it real. It took until Oct. 3rd, but the ultimate geeky fashion accessory is finally available.

* Mind Medley is a brain training-style program that has 16 different games, some of which can only be accessed by completing other games. You can try out some of the games for free with both Mac OS X and Windows versions.

* The scientists over at DribbleGlass.com have used their research to create an original and effective approach to memory technique that takes advantage of the differences between men's and women's brains. You can check out their memory breakthrough here (PG-13).

* Tired of the standard memory/concentration games? Try the perfect pitch memory version! Matching pictures is one thing, but matching tones is quite another.
