The LED Art Fan is quite possibly the coolest fan I have ever seen. I have no idea how well it cools down the room, because that isn't the main feature of this unique fan. This one has 42 computer-controlled super bright LEDs mounted on the fan blades that can display and animate pictures and logos. The fan has 5 MB of storage and can hold around 128 individual frames / pictures. It's an expensive but interesting alternative to digital photo albums on desktops, is great for advertising, marketing, logos and promotions, and its chrome art-deco design is very stylish. The downside is the the fact that people can now advertise on fans of all things.
