Dim My Chrome - my second Chrome extension
Hot on the heels of 8tracks Boombox, I created yet another Chrome extension - Dim My Chrome: Energy Saver
The extension dims down your Chrome pages after a specific amount of idle time (no mouse movement on the page), to save energy / save the planet, or just to stop nosy colleagues / bosses from being nosy! Simply move the mouse inside the page again to undim the page.
Dim My Chrome uses Background Page, Content Scripts and Message Passing. Check out the source on Github.
