TetriNet is a highly addictive Tetris-type game, which is designed only for play over the Internet. It features a built-in chat room, quite a lot of customizability, and best of all, it's free, no strings attached. You can download it from the Unofficial TetriNet home page.

Since I got ahold of this game, I've not only started to play it for as long as I can get away with, but I've started making themes for it. I'm posting all these themes online, so you too can use them in your TetriNet sessions. These games come complete with all files you need for the theme, in one handy ZIP file.

My TetriNet Themes

	The Rice-Boy Theme. This theme is meant to poke fun at certain groups of "performace enthusiasts" who would rather make their car look fast than go fast.
	Hawaiian Map Theme
	Radar Theme. This one is designed to improve playability, with color-coded special blocks, and a high-contrast, striped background.
