Even more video goodness for today - Blocks That Matter is an upcoming title for Xbox Live Indie Games, PC, Mac and Linux that appears to be some sort of platforming puzzler with Tetris elements.

Certain blocks can be collected and then placed down elsewhere, but only in the shapes of Tetris blocks. Complete a line, and it will then disappear, allowing you to progress. The Xbox version is scheduled for a April release, while the PC, Mac and Linux versions are penned for May. The Swing Swing Submarine blog has all the details.
