Foldplay.com lets you put four of your own photos onto a 3D moving paper sculpture known as a kaleidocycle.
Just upload your photos, or select some of them. They’ll slice, dice and stretch them onto a triangular grid. Print it out, score, cut, fold, and glue. They have a slideshow with complete directions. Presto! You have a personalized 3D paper sculpture with your smiling face turning around and around.
They’re easy to make if you have some experience with paper models.
