I've been hunting for 2 years. I gave up and went for tower fans. This is the best one I have found so far since it lets you cover a wider angle by splitting the tower:

I had to build a little shelf in my cabinet to elevate it, but I've seen someone rig a cool little shelf that attaches to the corner pole of a tent too. I will have to hunt for the post but it used some standard hardware store parts and some pvc coupler, I can't remember exactly.
