how this works

Each curve is sampled into a dense arc-length lookup table so particles and letters move at even spacing even when the underlying math speeds up or slows down.

• rose — petals from r = a · cos(kθ)
• lissajous — nested sine waves drifting against a phase offset
• hypotrochoid — classic spirograph machinery with a softer finish
• cardioid — a warm heart curve with a long glowing tail
• lemniscate — figure-eight ribbon tension
• fourier — harmonic sums that thicken as complexity rises

text mode uses pretext to measure graphemes off the DOM, then lays them along the tangent of the curve like molten captions.

the ambient drone is a tiny synth: one sine oscillator, a lowpass filter modulated by particle height, and a short feedback delay for a little air around the tone.
