Rollip is a one trick pony of a webapp, but if the pony you're after is one that can turn digital pictures into pseudo-Polaroid kitsch, you're in luck.
You can pick from a variety of technical errors that plagued Polaroid snapshots, like overly soft focus or hyper saturation, before adding text to the image.
The second step is selecting from a half dozen or so templates that offer different text and background patterns. The sample here is rocking what could be known as the Coffee Stain and Quirky Writing template.
If Rollip isn't enough to sate your web-based photo editing desires today, might we recommend blending your face with celebrities at MorphThing?
