A bit of fun
The Polaroin site converts dull, uninspired photos into dull, uninspired pseudo-Polaroids. It even adds vignetting like those cheap Polaroids did! The only thing missing is the smell of the chemicals used to fix the image. You received a tube with a wiper with each pack of film. After the image developed and you peeled off the paper (obviously, this was prior to the SX70) you wiped this stuff across the image to keep it from fading. Inhaling it was probably as healthful as sniffing glue.
That's downtown Tulsa last weekend, taken with a Pentax ME and a Phoenix 19-35mm zoom lens on Kodak 400 black and white film. The Phoenix is a craptastic lens by comparison to any name-brand wide angle, but it's still a lot of fun.
