craftgrrl | cool broken pottery bits?

hi all! i am thinking ahead past the holidays since most of my holiday gift crafting is done, except for the one scarf I have to knit for a friend and a little baking to do.

does anyone have cool ideas for what i could do with lots of different sized, broken bits of pottery? my brother's ex-girlfriend sent me a bag of different bits that are all shapes, colors, designs etc that she picked up on the beach. they are really beautiful and all so different... i wish i had a dig camera to post a pic. anyway, i've thought of the usual things such as making a small mosaic, drilling holes in them and making jewelry, or perhaps mobiles. i probably have about 4 cups worth and they vary from about the size of a dime to um.. about half the size of my palm. most are in between.

any other ideas out there? i checked the memories and didn't find diddly squat, unless i looked in the wrong place...

thanks!
