To follow on from Rocky's post, I thought I'd find a video to share of the fan, mostly as my initial reaction was "I bet it's noisy". I'm not a fan of his airblade hand purely for that reason.
So here's a video, the first thing is that it's a lot larger than I was expecting (from the images it looks like it's a small desk fan.) Secondly it doesn't seem as noisy as I was expecting, particularly on lower levels. What is particularly nice is the way you can just pick it up and carry it around - the fan is the handle.
Our only criticism would be that it's a very large object to place on a desk (although not much bigger than the fan it would theoretically replace) - would be good to create one that fitted around an existing monitor.
Great innovation... but hes just such a smug douche!!!!!!!
