Rubik's cube is a 3D mechanical puzzle, invented by Ernő Rubik. Each side of the cube is divided into 9 colored squares. The sides can be freely rotated so the colors get mixed up. The goal of the game is to find a combination of rotations that aligns the colors so that each side will have one solid color.
In Hungary, 15th March is national holiday, celebration of the revolutions of 1848. Turning the cube into this near-to-exploding position and taking the shot from the corner where red, white and green colors meet (these colors build up the tricolor flag of Hungary as well) was inspired by the spirit of that day.
