I'm having a crazy amount of fun with a $35 toy instant camera that prints on B&W thermal receipt paper.

Thermal receipt paper is cheap.

The camera also saves the native 8 MP color images to a micro SD card. The quality is about what you find on inexpensive cell phones.

I can make 4X6 inch color prints from those on my Canon G3260 for about five cents each.

I sill like to play with my Polaroid and Fuji instant cameras but those are expensive hobbies.
