Make a 2-minute sand animation that tells the story of 250 years of U.S. history. Keep it lively, engaging, and tasteful. Add appropriate background music and sound design.
Make it yours. Change "250 years of U.S. history" to your own story and "sand animation" to another hand-made medium. "2-minute" sets the length, and the last sentence asks for music and sound design.
250 years of America in sand animation
A two-minute sand-art animation of 250 years of U.S. history, scored with a medley of public-domain American tunes. It came from a three-sentence prompt in the Claude Code CLI with no edits; Claude wrote the code, the score, and the sound effects itself.

How it was made
Run in the Claude Code CLI. The creator says it was one prompt with no changes and no Blender, Three.js, or other tools: Claude wrote the code, checked its own work, and made the music. A follow-up post quotes Opus's account of the score: a Python script wrote every note to MIDI with mido at 96 BPM, so four bars last 10 seconds and match one scene. The medley joins Yankee Doodle, Oh! Susanna, The Entertainer, Amazing Grace, and America the Beautiful with original bridges, rendered through FluidSynth with the FluidR3 soundfont, plus procedural sound effects.

Sepia silhouettes on a sand-colored ground, each scene tagged with a year: a star ring around 250, wagons heading west, Lincoln beside broken chains, the Wright Flyer, the 1945 flag raising, and fireworks over the Capitol.
- Color
- Warm sand beige and sepia browns with near-black silhouettes, pale sunbursts, and one cool gray sand wash.
- Type

- Framing
- 16:9 silhouette tableaux on a low horizon, often with a sunburst behind the subject and the year in a top corner. Empty sand frames sit between scenes.
- Sound
- A medley of public-domain American tunes rendered from MIDI through FluidSynth, plus procedural sound effects, according to the creator's follow-up post.
- Structure
- A ring of stars around 250 with 1776 · 2026, a blank sand field, covered wagons and oxen heading west (1840s), Lincoln's profile beside broken chains (1863), a blank sand wash, the Wright Flyer on a dune (1903), the flag raising (1945), a gray sand wash, then fireworks over the Capitol and the Washington Monument.
