George Hart’s geometric sculptures, I really like the floppy disk one – “This is Disk Combobulation I, an assemblage of thirty 3.5 inch floppy diskettes, slotted and slid into each other gluelessly, embodying a precise five-color pattern. Each diskette is penetrated by diskettes of the other four colors. Twelve five-sided openings are each bordered by the five different colors in a different cyclic order. The six of any one color are arranged in the form of an exploded cube. For any choice of three different colors, there is one point where all three touch in a clockwise order; at the opposite point, they touch in a counterclockwise order.” – [via] Link.
