DDS Sine Wave Generator

I have not had a chance to experiment with this yet but it's pretty interesting. I ran across a project using an Arduino board from the Academy of Media Arts Cologne where they generate a nice looking sine wave in software from 0 to 16kHz. The project is found here

This picture from the project's web page shows the Arduino board with a low pass output filter and a picture of a generated wave form on the oscilloscope. behind it. The web site mentions they have used a similar system to generate audio tones for a WSPR project as well.
