Create a small fan that can plug into a spotlight socket, to replace the light or even to include a light. It might even be extendable to direct the fan ( see Pic of USB Fan example ).

I work in a small home office and don't have enough real estate for a large fan, and the small USB fan i have produces quite enough airflow. Looking at my Halogen light which shines on me, i thought why not have a fan there as well.

This means any wall mounted, or ceiling mounted light can be turned into a fan.

Kitchens, offices, kids playrooms, living rooms.... anywhere where a lightbulb might be fitted to a suitable light.
