A star sealed inside its own machinery, every watt of it spent on thought and nothing let out but the cooling.
A fully speculative artistic imagining, rendered procedurally, with no real hardware, mission or programme behind it. It pictures a matrioshka swarm: a star sealed inside five nested shells of computers that take its entire output and spend it on thought, each shell living on the waste heat the shell inside it throws off, until the outermost radiators shed the last of the light into the dark as a dull ember; the wedge cut through the lower right is a section, opened so the layers can be counted inward.Image: poweringspace.com.
