I like: Rollip.com
Polaroid pictures are artifacts of a bygone analogue age and the brand once synonymous with instant pictures is now used to brand digital cameras, printers, photo frames and software. Whilst instant film no longer exists, you can still have the same polaroid experience online.
Rollip.com is an online service that provides a service which converts a digital image into a good facsimile of a Polaroid picture.
Here is a before and after shot just so you can see how authentic the ‘Polaroid’ looks.
