A Chrome New Tab color clock. Shows a different colour for each second in the day e.g. if the time is 12:34:01, then the background and favicon will be the color #123401.

Get it on the Chrome Web Store - ColorClock Tabs.
Inspired by a post I saw on Product Hunt - someone mentioned that it'd be a cool New Tab replacement, and I thought so too - so I made it. A lot of these are floating around right now - mine is different because of the color changing favicon and (IMO) more readable code.
If you want to know what's going on, the guts of this are in ext/js/clock.js.
