I stumbled across the ALARMd.com Internet Alarm Clock a few months back, possibly via del.icio.us or Stumble Upon. I think the idea is great, and very well executed. With a large red font, and all black backdrop, the Internet Alarm clock is the perfect web based clock application I have found. The “Naken” mode makes it even better, eliminating the already minimal options and titles. For people that live with their computer, and try to eliminate all other necessities (like a cheap alarm clock) this clock is perfect.
The coolest feature I saw was the Alarm sound customization (pick an alarm), which allows you to open Pandora in a new window, which for most people with stored cookies should start playing your favorite music right away.
