This is cool in two ways, firstly it’s a fan to keep you cool and secondly you can use it to display animated pictures.
The LED Art fan uses 42 LEDs mounted on the blades to create a moving picture. It comes with an IR transmitter so that you can program it from your PC (serial port required). The resolution of the fan is 85 pixels (diameter) and the 5MB of storage is enough for 128 images.
I must admit it seems a bit strange to describe a desk fan by means of resolution and storage capacity but then again watching a home made cartoon on the office fan isn’t exactly an everyday thing.
