The Dubberly Design Office recently published a poster depicting “the 892 unique ways to partition a 3x4 grid into unit rectangles.” This project was inspired by a patent received in 2006 by William Drenttel and Jessica Helfand of Winterhouse ("Method and system for computer screen layout based on a recombinant geometric modular structure," Patent No. 7124360) that modeled screen-based grid systems.
Here is a 100-second animation, which is based on the poster, cycling through all 892 variations. Read more about it here.
