Usb fan with LEDs

Look at the fun fan that I bought in China. It has leds on a blade and generates a geometric pattern when it spins.

The body is metal and settles in the position you want. I thought it was just a little too heavy for the conventional USB connector support.

For a key switches on the fan body. You can see, in the picture below, the trail of SMD leds.

When he calls several geometric patterns are generated. It seemed random, but there must be a standard. Surely there's a built-in microprocessor, but I don't understand where you are.

Almost no fans nothing, but it's pretty fun to watch!

Left it on almost 1 hour and not burned. General test of Chinese product: No fans but also doesn't burn.

Of course I couldn't record a video. Check out all:

I leave the link of DealExtreme. For a little less than $ 4 you can also have fun with this mesmerizing fan:
