As you all may know, I am quite obsessed with Rubik's cubes. They were created as a tool to help Ernő Rubik's architecture students visualize three-dimensional concepts, but modern artists have utilized his six-colored creation as a medium for mosaics. Because stone tesserae were, naturally, too boring. These guys orient the pieces of the cubes (Rubik's cubes have an amazing mathematical nature to the ways in which the pieces can be moved, which I could go on and on about. Look up some introductory Group Theory if you have an afternoon of leisure time). While the pieces range from the frivolous, like Spongebob and the internet "troll" face, to the beautifully intricate. My personal favorite is Josh Chalom's interpretation of Michelangelo's The Creation of Adam. Here's the original fresco:
And here's Chalom's "Cubist" (heh) rendition:
Normal Cube-mosaics consist of about 800 Cubes; Chalom's used a record-setting 12,090.
