I used to have a little Polaroid camera. I loved the way that the pictures appeared over time, and the strange way it had with colours. Nowadays such technology is being replaced by digital, but the Poladroid application does give you a way to recapture that old magic. It takes pictures and gives them the Polaroid treatment, right down to the borders and the way that they take time to appear. You can actually watch the image develop, and even take snapshots of the slowly appearing picture.
You can get the application from: http://www.poladroid.net/
A couple of snaps which have been converted.
Then again, Polaroid might be making a comeback:
