What the hundred games are built with, what we reach for next, and where to look if you want to see how.
THE PROJECT
Build LedgerEvery project, measured from its own git history. Days, commits, lines, what is live.
RelayThe house template for daily link-first games. Two files of game, everything else built in.
Silly Ninjas artEvery sheet in the Silly Ninjas kit: the five ninjas with their poses and emotes, and ten worlds of props, ground and cast. Shared by Silly Ninja Defense and Silly Ninja Squares.
The trayOne script tag gives any game EJECT and SUBSCRIBE. It renders in a shadow root so it looks the same in every codebase and touches none of them.
THE PEOPLE
Dan ViauBuilt tally, the analytics in every game, and the Zen redesign of Hex Smash that became the house look. Also the arcade hub and Hex Smash Ninja.
Gustavo KonradRebuilt Lore Wars and BREACH on Solid, and built Wizard Battle and Overland.

THE CARTRIDGES
Ten Midjourney photographs of cartridges, cut out with real alpha.A cartridge outline is not something a rounded corner can fake, so the silhouette is computed: colour distance against a per-scanline ground model, forced convex, with a separate shadow test used only to trim inward.
Each label is the game running.The ledger photographs every live game. That plate is printed into the photo window of the shell the game was dealt.
The sound is synthesised.Web Audio, scheduled on the audio clock so the seat lands with the cart and the chord with the light.
