T3DRIS by Return Null
It's basically 3D Tetris. In Tetris you run out of space if you don't carefully consider your block placement, it's the same in 3D Tetris, but with an extra dimension.
Made with the help of my own OpenGL engine, which doesn't have sound support yet so there is no sound. The game has a steep learning curve, but once you have climbed that curve you will be rewared by pure happiness and a high score.

Controls:
WASD : Move the block
SPACE : Speed up the block
Mouse : Move the perspective up and down
Q : Rotate block around the Z-axis
E : Rotate block around the Y-axis
P : Pause the game!
TAB : Switch projection mode between perspective and orthographic

Btw, adding all the possible type of the tetracube would be cool.
