Zach Leatherman's Alarmd is a web-based alarm clock that offers up a unique selection of alarm types, from the tradional sirens, to the sound effect of a passing train, to an interesting choice of YouTube music videos, and both Last.FM and Pandora online radio channels. You can even insert the web url of any online media source and use it as your wake-up call. As an alarm clock there's plenty of custom settings, from colour and text size of the clock display itself to the option to set a Key Mash Mode where you have to randomly type five keys on your keyboard in one second to get the alarm to turn off.
