If you take a lot of pictures on your iPhone, I can highly recommend the Canon Selphy CP900, a dye-sub photo printer which spits out 6×4 prints, and connects wirelessly to iPhones, iPads and Macs.
I’ve had one for a couple months, and the result is that I have a bunch of iPhonographs littering the apartment. It’s addictive, but now I don’t know what to do with all these prints. This graffiti-ready picture frame, though, might provide an answer.
The Parrot DIA (pronounced like the Spanish for “day”) is a weird little gadget that also manages to be very cool indeed. Its main purpose is as a digital photo frame, but even there it fails to be dull — the screen is actually transparent, so it displays your photos like old-school film slides.
