Cool Arduino Clock

Here is a pretty cool clock done using a platform similar to the Arduino, all of the software and code is open source and available on their site. A fully functional clock with all of the regular features of a normal alarm clock such as:

• Cool glowing blue tube with 8 digits and alarm on/off dot
• Adjustable brightness
• Alarm with volume adjust
• Precision watch crystal keeps time with under 20ppm (0.002%) error (<>
• Clear plastic enclosure protects clock from you and you from clock
• Battery backup will let the clock keep the time for up to 2 weeks without power
• Selectable 12h or 24h display
• Displays day and date
• 10 minute snooze

Just something I thought was interesting. The plans are a bit more complex than anything we've looked at yet, still something I thought was interesting.
