I always wondered what my photos might look like as a calendar. Well the clever, clever folks at bighugelabs created an interface that allows you to make a monthly calendar using any photo you want.
All you have to do is load/link the image and print it out. Prints are full size or can go down to the convenient size of a CD case. I tested it out using a photo I have here at work, I think it came out kinda snazzy.
