Remember the days before digital cameras when all you had were good ol' film canisters? (I'm pretty sure I still have 4-5 of these undeveloped rolls hiding in a box somewhere.) If you happen to have some around, you could repurpose them by turning them into USB drives, like Photojojo! did. Not into trying it yourself? Buy one of the rolls they've already upcycled. You might get a Fuji Velvia, or a Tri-X, maybe even the elusive Kodachrome.
