This is Object 6-C, a Lego MOC by Mitsuru Nikaido. This object is five Lego rings that seem to melting. With blue, black, red, yellow and green drips. The drips of color are all instantly recognizable. The circles themselves are very impressive. A bunch of 1×1 blocks with studs on all sides, and a lot of black joints. A very simple, and very effective way to build a circle out of Lego.
