These are not screenshots of tools. They are the actual mechanisms, reimplemented small: the fee-band routing behind a mempool visualiser, speculative decoding and the cost of a forced reflow, the 121 GB-per-Spark memory budget that decides what can sit at once, the interference pattern used as the motif on both sites, and Host — an original gorilla you slash-command.
- 01 · ~1 min Fee-band router Transactions arrive, get sorted into fee bands, and race for space in the next few blocks. Drag your fee rate. Watch which block takes you — or climbs past you. canvas · simulatedOpen →
- 02 · ~2 min Speculative decoding A small model guesses ahead; the big one checks the whole guess in one pass. Drag draft length k. Watch the speedup peak — and fall past it. canvas · measured shapeOpen →
- 03 · ~2 min 13s → 7.5ms A real O(N) render bug, reproduced: one click, two implementations, timed live. Drag rows. Your browser does the timing. DOM · your machine times itOpen →
- 04 · ~1 min 121 GB packer Each Spark is a 121 GB tank. TP2 fills two of them. A third is a spare. Pick 1 / 2 / 3 Sparks. Tap a model. Watch the tanks fill. TP1 · TP2 · measuredOpen →
- 05 · poke around Moiré bench Two grids, slightly disagreeing. The third pattern is not in either layer. Nudge Layer B spacing one notch. The bands you see are the disagreement. canvas · site motifOpen →
- 06 · poke around Host Original gorilla with a frohawk. 4-dir sprites, slash emotes, no backend. Tap /twirl. Then /walk /roar. He does not morph. sprites · slash cmdsOpen →
