Saw an interesting application in the App Store today called WordFoto. As you can probably surmise, they add words to a photo. The process is simple enough, and the program is very responsive on my iPod Touch. All in all, it was worth the 230円. The only request I have is the ability to create lists with more than ten words, as it's hard to sum a person up with a handful of keywords.
Next time I think I'll update an avatar with the top tags on this site.
You can find WordFoto on the Apple App Store.
