Here's a neat little Tetris game built entirely with JavaScript
and Dynamic HTML. To play this game you must use either Netscape 4.0 or Internet Explorer 4.0 - although
I highly recommend you use Netscape because the game runs much faster in it. Also, if you use Netscape on
Win95/NT you should hear the 2-song MIDI soundtrack to the game.
Due to JavaScript limitations I couldn't make the game super-fast, and to compensate for the higher levels
I made the blocks make bigger jumps. On level 13 (if you're that good) you'll notice it.
