I am reminded of this passage (set in Akihabara) from Neal Stephenson’s Cryptonomicon:
The place is laid out precisely like an Asian food market: it is a maze of narrow aisles winding among tiny stalls, barely larger than phone booths, where merchants have their wares laid out for inspection. The first thing they see is a wire stall: at least a hundred reels of different types and gauges of wire in gaily hued plastic insulation … An array of soldering irons bristles wickedly, giving one stall the look of a martial arts store. Coffee-can-sized potentiometers are stacked in pyramids.
… A pasocon otaku in a trench coat, holding a plastic bowl as shopping cart, hunches over a display of gleaming copper toroidal coils that look to have been hand-polished by the owner. Finger-sized halogen spotlights mounted on an overhead rack emphasize their geometric perfection.
… They wander past a stall that specializes in banana plugs, with a sideline in alligator clips, arranged in colorful rosettes around disks of cardboard.
… Avi stops in front of a stall that sells LEDs in all manner of bubble-gum colors, packed into tiny boxes like ripe tropical fruits in crates, and standing up from cubes of foam like psychedelic mushrooms.
Whatever his shortcomings may be (some consider him wordy, for example), Stephenson is a master of metaphor and simile. (LEDs “standing up from cubes of foam like psychedelic mushrooms”, indeed.)
