I created a Tetris clone in Java.
These are the controls for the applet below:
|← and →||Move brick left or right 1 position|
|Ctrl-← and Ctrl-→||Move brick left or right as far as possible|
|Shift||Turn brick clockwise|
|↑||Turn brick counterclockwise|
|↓||Move brick down 1 position|
|CTRL ↓ of Enter||Move brick down as far as possible|
