USB Floating Ducky Humidifier
So you have a coworker who loves cute little things? That USB Duck Humidifier can be what you were looking for! This duck will float in a glass of water, suck the water from it and release a nice fresh steam. The moisture is generated by cool ultrasonic waves. The USB cable to plug it in is 1 meter long, so you can put the humidifier quite far from your computer if needed.
