what's in a paint can?

I like the looks of paint cans. Everytime i go into Home Depot, I admire the empty, shiny, monochromatic, purposeful looking containers. I recently brainstormed and tried to make a list of some cool uses for them. Add your ideas into my comments section.

Uses for empty paint cans..

1- Pots for plants, make sure to poke drainage holes first.
2- Wrap the containers in fabric or paper for an interesting way to present gifts.
3- Small cans make perfect holders for crayons or small kid stuff.
4- Big cans make purrfect holders for cat food.
5- Nail the bottoms of the cans against the wall in your garage for storage of nuts and bolts.
6- Punch holes in them with a metal punch and add an inch or so of sand, make great christmas luminaries.
7- Contain stuff (cosmetics etc) under a sink.
8- Cheap and funky alternative to ice buckets!
9- Storage for random golf balls your dog finds on her morning walks...
10- Cut a slit in the lid and decorate for a cool piggy bank.
11- Small cans lined up on a shelf above your desk can hold pencils, pens, markers and other random desk supplies.
