OK, I love LEDs, they use very little electricity, they are very little, they give a much nicer light than fluorescents and they can provide a range of color changes when mounted in combinations. I posted about a cool LED clock recently and here is a really cool programmable LED fan. It has 42 LEDs mounted on the blades that create moving color images when they spin, up to 128 frames.
Implications - Consumers will enjoy this programmable LED fan due to its combination of practicality and enjoyability. A "fun factor" is becoming an increasingly important part of the buying process, since so many products are now multi-purposeful and fuse entertainment and functionality.
