Friends of the Web, a four-person Web tech firm in Baltimore, spent a weekend in February building Jittergram at a photo hackathon in New York City.
They figured, hey, it's a simple iPhone app that helps people create animated .gifs -- might as well just put it in the Apple App Store.
You take two similar photos, the app mashes them together, and you have a defacto animation. Fun. quirky. Easy.
They launched it this month and the downloads started trickling in -- until Apple featured Jittergram in the prominent "New and Noteworthy" section in the App Store on iTunes.
The downloads for Jittergram have taken off -- the little app, still a little unpolished, but simple and fun to use, has more than 100,000 downloads for Friends of the Web, according to co-founder Andy Mangold.
