How do you make Tetris better? You could always try playing it using Terran buildings in the Starcraft 2 beta.
You might want to turn off the sound, since the Tetris jingle can't drown out the mechanical cacophony, but that's OK. You don't need the sound. Just the visuals, and the knowledge that someone, somewhere, found the time/effort to actually do this.
I've been playing the Starcraft 2 beta for a while now, and not once have I come across any slowly-cascading Russian blocks. Maybe I'm playing at the wrong time of day.
