If you haven't converted to digital photography, or you're a packrat who still has empty photo film canisters, you can make your very own salt and pepper shaker by punching holes in the lids!
Or if you have more money than creative talent, then you can buy a set by Rita Bothelo for $35 (Whaaat!?). Perfect for the photography enthusiast in your family: Link
Update 11/8/07: Maybe this is a bad idea, guys - there may be bad chemicals left by the film or even in the non-food-grade plastic itself (see comments).
@Mary Bon #6, no it wasn't a paid product placement on Neatorama. Those are disclosed. From time to time, I do blog about neat products that I run across the web.
$35!?! I hope this was a paid product placement.
