01 — THE SCREENING ROOM
Six new stories, three compact starters.
Different worlds. Different soundtracks.
All made with Looplilt. All yours to explore.
01 / PIXEL ADVENTURE
A storm, a stranded boat, and a lighthouse keeper with one last battery. Five shots move from a sleeping harbor to the machinery inside the tower.
THE SCOREStrings, plucked melody, a restrained chip lead, and coastal weather.
02 / JAZZ-CLUB COMEDY
A newcomer arrives at Small Hours with a triangle and terrible timing. An accidental foot tap becomes the missing piece of the band.
THE SCOREPiano-like keys, walking bass, brass, brushed drums, and a well-timed triangle.
03 / ART DECO POSTCARD
Across a moonlit viaduct, the last train follows a small light home. Layered scenery gives way to a close view of the person waiting at the platform.
THE SCOREA lilting string-and-piano waltz with a slowing railway rhythm.
04 / LUMINOUS MOTION
Two signals can see each other but cannot connect. After a collision, one discovers a route above the city. A detour becomes a shared rhythm.
THE SCORELayered electronic groove, rounded bass, pads, percussion, and a warmer final chord.
05 / INK ON PAPER
A curious fish nudges a drifting leaf. The leaf wakes, turns, and joins it. A small encounter told with brush-like marks, ripples, and space to breathe.
THE SCOREPlucked strings and marimba trade phrases above a quiet pond ambience.
06 / ISOMETRIC MINIATURE
Two friends are separated by a roof. A tiny helper steps onto a counterweight, turning an idle pulley into a way to meet.
THE SCOREA music-box ensemble with plucked strings, soft piano, and timed mechanical details.
07 / PAPER-WORLD STARTER
A little rain, a patient seed, and a visitor with excellent timing. Begin here to explore texture, growth, and the browser remixer.
THE SCOREA compact, gentle procedural melody.
08 / EXPLANATION STARTER
Follow a point around a circle. Keep its height, trace its past, and a wave appears. A small starting point for an explanation of your own.
THE SCOREA regular pulse that follows the geometry.
09 / PIXEL-COMEDY STARTER
One robot. One parcel. One unusually particular door. A short starter about staging a readable visual punchline.
THE SCOREA playful compact score with timed accents.
Every film is an editable project. The six new stories use Looplilt’s stereo sound studio; the compact starters keep the simpler original scores. Wide and tall versions are composed for their frame.
02 — INSIDE THE LITTLE STUDIO
Two project files. A whole creative loop.
Plain JavaScript, with room for your imagination.
01 / MAKE A SCENE
Your timeline lives in project.json. Your world lives in draw.js. Shapes, characters, charts: it is all editable.
02 / FIND THE FEELING
Open a standalone player. Scrub, replay, and tune the timing. Add a procedural score, captions, or your own narration.
03 / SEND IT INTO THE WORLD
Render wide, tall, or square MP4s locally. Keep the source beside the finished film, ready for the next idea.
03 — YOUR TURN
Start with a seed. Change a color, a shape, a moment. Your first film is only a few commands away.

OR, START WITH A CONVERSATION
Give this prompt to a coding agent with file and terminal access. It will aim for a working HTML film first, then add video tools when you need them.
Installation details & compatibility ↗No Looplilt account or API key. Your agent needs permission to work in your chosen folder.
MADE TO BE MADE YOUR OWN
A tiny story. A clearer explanation. Something wonderfully odd.
There is room for all of it.
