USB : USB Mushroom Humidifier

Yes, I know it looks like I have fungal growth next to my desktop (and a forest behind my desk). I DO have a forest behind my desk, but that cute little mushroom is actually a humidifier. The water goes in the stem. Air is filtered through the mushroom head and circulated via its internal fan motor, and then released through the vents. It can run on batteries or charge via USB.

It's 2,362 yen and you can buy it here.
