Sure, Snapshot Frames turn any picture into a magnetic Polaroid-style photo. The set of five 3 1/2" x 4" magnets is only $10; just slide your photo into the frame to turn it into a Polaroid.
These would make a cute Valentine's Day gift for your sweetie. They're much cooler than most of the geeky picture frames I've featured. The fact that they're magnets makes them even cooler and would be a sweet retro touch to your fridge.
