Sony PSP cooling fan
Some people are really creative in inventing accessories for the PSP.
A Japanese vendor called GameBank is listing a "PSP cooling fan" in their product catalog:

The
fan goes for 980 yen (~$8.35), and is fastened to the top of your PSP
by screwing it into the holes on either side of your USB port. It has
an internal rechargable battery, and can be recharged using the same
charger as you use for your PSP. Recharging takes 3 hours.
So
usually you would ask for the sense of this. My first idea on this was:
stupid! But when you get to the point that the fan is not to prevent
oberheating of the console but to prevent your buttons and hands from
getting sweaty while playing the idea becomes not that bad...
