One prompt · One attempt · One file — each
A collection of real interactive simulations — chaos theory, fluid dynamics, emergent flocking, Fourier analysis, algorithms — each one written in a single attempt by Claude Fable 5. No frameworks, no fakery: open view-source on any of them, the whole thing is one file.
100 double pendulums released 0.0001° apart — watch them agree, then explode.
Real: exact equations of motion, RK4-integrated at 240Hz in float64. The divergence is measured, not scripted.
Open →Thousands of starlings flock like the real thing. Your cursor is the hawk.
Real: Reynolds boids — separation, alignment, cohesion from actual neighbors via a spatial hash. The shapes emerge.
Open →Pour living ink into water — a GPU fluid simulation you paint with.
Real: Navier-Stokes in WebGL shaders — advection, vorticity confinement, Jacobi pressure projection.
Open →Draw anything — a chain of spinning circles redraws it perfectly.
Real: a discrete Fourier transform of your sketch. The circles are the Fourier series, reconstructed live.
Open →Four sorting algorithms race on the same bars — every comparison plays a note.
Real: genuine implementations as generators; sound and visuals are driven by the actual compare/swap events.
Open →Prompted Fable 5 into a one-shot simulation where the depth is visible? The collection takes PRs.
Bar: one self-contained file, real algorithms (we check the source), honest one-shot statement.
