On-line Flash games. Indie game developers conspire to make sure you don't get anything done.

Bloxorz: 33 levels of block-flipping brain benders

Desktop Tower Defense: Addicting until you realize the number of optimal strategies is actually very small, and to score really high you have to learn to "juggle," dynamically changing the maze while invaders are moving through it. Still, it's pretty cool.

Boomshine: Neat name, simple game. I like the music.

Flow: Designed as part of a Master's thesis. I like the atmospherics, and even though I'm not crazy about the actual game play, it's kind of hypnotic and relaxing.

But don't blame me if you don't get anything done today. You clicked the links.
