I've always kept a small fan on my desk at work.
Since I'm a fat bastard, walking around at lunchtime generally leaves me horribly sweaty, so I like to be able to cool down when I return.
Sadly, every small fan I've ever found looks incredibly boring, if not downright ugly.
So, I was pleased to see the nice design of the La Luna by Studio Hideki.
Presumably, there's a set of vertical blades inside, revolving around a central hub. I hope the holes are only open on one side, so you can control the direction of air flow.
Unfortunately, I can't tell whether this is actually available or simply a prototype design.
