Emoticon badge makes your mood clear

Sometimes the simplest ideas are the best.  If you’re tired of answering people’s inane (and insincere) “how’re you?” questions then perhaps you need one of these emoticon badges.  A button on top lets you cycle through the stored LED patterns, so you can easily flick from “sad” to “super-happy” when someone offers you a free coffee.

DIY with the instructions and parts-list linked from the Flickr gallery, there’s a video of it in action here.
