The amazon remembers feature of their iPhone app is quite hilarious, and very good. I took photos of lots of bits of office stationery, and it recognised them very well—including a small yellow post-it note pad, some gum and various other random bits.
It seems they’re using their mechanical turk service. It is a bit disappointing that it’s not automated, but a cool application of ‘old technology,’ too, I guess.
Addendum: I tried writing “Ideal $10 gift for co-worker” on a post-it note, photographed it, and promptly got this product suggestion. Nice job :)
