Instant, Retro Polaroids on your Mac

This post is off topic (as it's related to a none iOS app), but I thought many of you Mac owners would be interested in a new'ish app called "Instant", which is currently on sale in the Mac App Store for just £2.99/$3.99/€3.19. Instant aims to bring the fun of Polaroid instant photography to your desktop, by letting you "Re-shoot" (load) your digital photos, wait for them to "dry", before that classic Polaroid look with border is revealed.

Instant features:

• Realistic and fun UI and workflow. Instant mimics the workflow of a real Polaroid instant camera. Drag and drop your photo on to the camera, a view finder will pop up. Carefully select your field of view and click 'Shoot'. A picture framed with Polaroid classic border will slide out. Wait for it to "dry". Slowly the developed picture will finally show!
• 28 vintage effect filters including 8 classic Polaroid filters. Each filter can adjust intensity, vignette, emulsion and blur effect. 
• Add hand-writing comment on the border, just like the really thing. Choose from 10 elegant hand-writing fonts. User can add their own fonts.
