Ok, how about some new ideas?

- Massage rollers. They sell wooden ones that are simular in Body Shop.
- Sexual Aides. Use your imagination.
- Furniture moving wheels. Very light furniture that is.
- Flying kite string holders.
- Handmade doll cart wheels.
- Juggling toys.
- Painting, mark making tools
- Hairdresser's hair tangling rollers.

Come on people, I need more contributions to this genuinly useless research!
