I got my hands on a fan today.
A USB Fan.
An Oscillating USB Fan.
It used to have a grill to make it look like a real desktop fan, but it was getting in the way of the blades, so I removed it (it can be seen on the stack behind the fan) but.. more problems, now it's too light so it starts moving around when it's on.
Maybe that's why they use gooseneck cables for USB fans usually?
