The Japanese Sensu handheld fan USB is a perfect solution to the often wasted fan. Now instead of it lying around when you're not hot (or for a geisha, performing) you could be using it for up to 16gb of storage.
I always found something slightly (more than slightly) attractive about those beautiful geishas waving their fans so gracefully around the room. What if those fans had a little more important things to do? The Japanese Sensu handheld fan USB is a delightful and deceitful piece of computer technology.
