Instant is a newly launched Mac application that brings an Instagram-esque, Polaroid-faking app to your desktop. It allows you to turn any digital photograph into a Polaroid picture look-alike, and offers 28 different filters for giving your images vintage looks (8 of which are designed to look like Polaroid films). You can even add classic Polaroid frames to images and jot notes onto them. The app costs $7 and is available from the Mac App Store.
