I remember someone on the forum had this thread about taking requests to make a program.
Someone replied and requested a program which converted regular 2D images and converted them to 3D, although it seemed as if he wanted the image to be converted to random colors, not 3D specifically.
Although this does not let you convert images, it lets you convert something cooler -- videos.
If anyone really wants this program to convert pictures to 3D/random colorways, you can take a look at the project's source code.
The project is part of a collaboration between MIT's Computer Science and Artificial Intelligence Laboratory (Twitter: @MIT_CSAIL) and Qatar Computing Research Institute (Twitter: @QatarComputing).
