POV Christmas Tree

You have probably walked through an airport to see one of those fancy spinning screens which seems to always face you. You have also probably seen the frisby with a bank of LEDs on which you can throw and it spells out words in the air. The POV Christmas tree works on a similar principle. It is a bank of LEDs in the shape of a tree. The LEDs spin around a central point fast and it shows the appearance of a christmas tree out of LEDs. They are cool to watch. The tree is powered by 9V batteries and full instructions can be found at the link at the bottom of this post.

For those of you who are not sure what POV means, it is persistance of vision.
