Tiny Prism designs, ships, and operates a handful of independent web products — Hexagram Cast, Holdem Method, DIANJI, Oddly Hard, and LLC Deadlines, with more in the works. This site is the studio's home base, not a sales pitch.
Tiny Prism LLC is a founder-led, one-person studio. Its main job is to design, ship, and run the products below — and there are more of them in the works.
Founder-led · Wyoming LLC
Building for the web since 2005. Tiny Prism LLC is the entity that owns, hosts, and answers the support email for everything below.
Each product started as something worth using, then got built well enough to run for real — its own domain, its own design, its own users. Tiny Prism is what operates behind them: it holds the registrations, pays the hosting bills, and is the legal entity of record if one is ever needed.
There's no sales process here. If one of the products below is useful to you, use it — the links go straight there. If something else brings you here, including a possible collaboration, say hello.
Five independent products, each live, each designed, shipped, and run in-house — with more in the works. Tiny Prism LLC is the operating entity behind all of them; every product keeps its own name, design, and users.
Cast a hexagram from anything — and check the math.
Resolves coins, yarrow stalks, a sentence, a photo, or a song into the same six-line structure across eight methods, and shows the computation trace behind every cast. In English, 简体中文, and 繁體中文.

面向现代读者的中国经典 — Chinese classics for modern readers.
A bilingual reading tool for Chinese classical texts, linking each passage to its translation, annotations, and sources so a classic is easier to browse, compare, and study.

Your US LLC has dates. Here they are.
