Remix a film made entirely of code, and post it as a Reel

Window Seat, Roost and the other risograph films from our reels are each one HTML file: no video, no images, just code that draws every frame. Change the colours and the fireworks, then export your version as a vertical Reel with sound.

Before you start
  • Level 0 done: Git and Node.js installed
  • FFmpeg for the last step (see Shrink, trim and reformat any video)
  • About 1.6GB of disk space (the repo, plus the browsers the export tools use)
  • A text editor. Notepad works; VS Code is nicer

STEP 01 of 06~5 min

Download the films and press play

See what a film made only of code looks like, with nothing installed but Git.

  1. These commands work the same in PowerShell, Terminal on a Mac and a Linux shell:

    Terminal
    cd $HOME/Downloads
git clone https://github.com/sevenevesai/riso-windowseat
cd riso-windowseat

  2. The download is about 93MB. Now open your file manager, go to riso-windowseat/films/window-seat and double-click index.html. It opens in your browser, offline.

    Window Seat open in Edge at 26 seconds: a night city through a train window, with Play, Replay, a time slider, Sound and Record buttons
    Window Seat at 26 seconds. Everything you see, including the halftone dots, is drawn by code in that one file.
    • Play and the slider: watch or scrub through the 78 seconds
    • Sound: off: click it to switch the piano score on (it takes a few seconds to prepare)
    • Try the other folders in films: roost (starlings), held (a kite), nonpareil (paper marbling), eclosion (a butterfly) and more
    TipThe live player draws every frame in real time, so on a laptop without a graphics card it can stutter (around 9 frames a second). The film itself is fine: step 5 exports it frame by frame, perfectly smooth.

On the GitHub page ↗ click Code, then Download ZIP, and unzip it. You'll still need Node for steps 3 to 5.
