If you haven't already been over there this weekend, check out Grey Matters Videos! This weekend, we're featuring new videos of some very brainy kids.

There's Shecharya, who can recall 106 digits of Pi, a 4-year old and a 6-year-old, both of whom can solve the Rubik's Cube, and footage from a 4th-grade mental math competition.

These aren't the only kids ever posted on Grey Matters Videos, either. If you've ever seen them, you certainly can't forget Abby Julo, Florian Osmani, Xaver Neuhausler, Fabrice Becker and “Elliott”!

While I'm talking about the video section, I should also mention the new Grey Matters Video Channel over on YouTube. As I add new videos from YouTube, you'll be able to find them on that channel, on the Amazing Mental Feats playlist, or in this Grey Matters Video entry.
