Generators that draw rather than pick: a heraldically correct coat of arms, a perfect maze with exactly one way through, and symmetric mandala or spirograph line art.

Everything in this group is drawn, not looked up: each press pulls a fresh seed from cryptographically secure randomness and unfolds a whole design from it deterministically, so any result can be recreated from the number stamped on its card. The Coat of Arms generator composes real heraldry -- field division, tinctures, charges, and a Latin motto -- and writes out the formal blazon that describes it. The Maze generator carves a perfect maze whose single solution it can draw on demand. The Mandala generator lays down radially symmetric line art, or traces a spirograph curve that closes exactly because its gears are whole numbers. All of it is vector-drawn, so screenshots and prints stay crisp at any size.
Every result here is drawn using crypto.getRandomValues() -- the Web Crypto API's cryptographically secure randomness -- instead of Math.random(), so it's genuinely unpredictable, not just statistically random. Learn more.
