TechCrunch reports on a Googler, Paul Truong, who created an HTML5-based game for Gmail called Galactic Inbox using his 20% time:
When you start it up, a little Gmail logo envelope guy pops out of a “20% Projects Lab” and starts flying. Essentially, he’s a spaceship and can shoot objects coming his way. It’s simple, but [...]

Slither is a Web port of the age old Snake game.
Erik Johnson wrote the game, and had this to say about the project (available here on GitHub):

We’ve seen a million varieties of snake/nibbles games over the years, especially in Flash; however, I haven’t come across many that are implemented using Canvas. I’ve used it to [...]

Nearly 4 years ago, Ben Joffe created a fun Tetris-like game called Torus that takes the classic and makes it cylindrical. He just updated the game now that browsers can power his canvas game sooo much better.

Slightly higher playing field

Visual indication of death zone

“Sparkling” blocks

New points system

New piece types [...]

On Firefox we have Vimperator and now on Chrome we have Vimium:

Vi users rejoice!

David Friedman calls is “silly”, but he has created something simple and fun in his new form of volume control that moves from whisper to shout as you change the volume.

The code (which works on Firefox and Opera right now) uses different tracks for each level:
