Invader, a former French street artist, pioneered Rubikcubism—an art form using hundreds of twisted Rubik's Cubes arranged in pixelated patterns to create images ranging from 8-bit video game characters to famous faces and historical figures. Other artists like Toronto-based Robbie McKinnon have adopted similar techniques, using either manual arrangement or computer programs to recreate complex source images as large mosaic works weighing around 80 pounds.
