I only watched the 2nd video, but I wonder what happens when you miss.

It reminds me of that one game show, I believe it was called "Hole in the Wall" here in North America, but may have actually been titled something like "Human Tetris" in Japan. Looks like it could be fun, I might download it if it were to make its way here.

This is a pretty nice idea. I haven't really seen anything like this.

It was called Brain Wall, although English speakers sometime referred to it as human Tetris since that it was it looked like.

Whoa.  That actually looks pretty cool.  I didn't listen to the music, (in a mute-necessary situation), but with some driving tunes that could be a fun, intense puzzler.  (And an aside: Bring back Tetrisphere!)
And that TV show was ree-diculous.
