Polaroid images

Can someone advise the best way to make a digital image look like a Polaroid shot through Photoshop?

Which type of polaroid?

Years ago i played around with trying to re-create the sx 70 manipulated look. Used plastic wrap and liquify, got the look but just missed the color palette.

somewhere in my files i have a program that turns an image into a polaroid type image but will need to do some hunting to find it. i believe it was free.

Thanks ann and wouldn't mind a copy if you find it. The sx70 look is fine.
