Every Watt, Spent Thinking

A star sealed inside its own machinery, every watt of it spent on thought and nothing let out but the cooling.

An artistic imagining, not real hardware. A near black indigo square with one blazing white star a little left of centre, wrapped in five nested rings of machinery drawn face on. Each ring is built of hundreds of small flat panels: the edge of every panel that faces the star is a pale lit collector face, and across each panel runs a short row of brighter cells, densest and whitest on the innermost ring and thinning to a few scattered sparks on the outermost. Short radiator fins stand off the outer edge of each ring into the gap beyond it, and each gap is filled with flat stepped bands of glow that are bright cyan close to the star and fall away to deep indigo further out, so the picture cools from white at the centre to abyssal blue at the rim. Beyond the last ring, dull rose coloured dashes drift off into the dark. In the lower right a wedge is cut through the whole nest as a technical section, and inside it the five layers stand stacked as slabs with lit inner faces, ribs and cut radiator stubs, the space between them flooded with the star's light. The dark margins carry pasted fragments of a celestial diagram: thin orbit arcs, graduated tick scales and stars drawn as short arc dashes, all cut from circles about the same centre and glued back very slightly askew. No text, no insignia; nothing shown exists.
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.
