How to put a moving scene behind your terminal shell with Limoni

Run backdrop-shell so an animated scene sits behind your shell text in any terminal.

Authorization notice. Limoni is dual-use. Only use it on software, sites and systems you own or have explicit permission to test.

Remote script. The install command pipes a script from the internet directly into sh, so read install.sh first if you do not trust the source.

Who it is forA terminal user who wants a decorative animated background without slowing down their shell.

The problemMost terminals show a plain background, and adding a moving scene usually costs CPU and clutters the text.

The outcomeAn animated scene behind the shell, with the text in front kept sharp and adjustable opacity that changes in every open terminal.

What you need first

  • Go toolchain installed (for go install, go get, go run and go test)
  • A terminal that supports the app's output (images and some features depend on the terminal)
  • For the MCP use case: an MCP client such as Claude Code or Cursor, and limoni-mcp available on PATH (the README does not show how to install it)
  • For the backdrop use case: curl, sh, and a terminal emulator

Steps

  1. Run curl -fsSL https://raw.githubusercontent.com/thebanri/limoni/main/apps/backdrop-shell/install.sh | sh
  2. Run backdrop-shell enable -scene synthwave to turn on the synthwave scene
  3. Run backdrop-shell opacity 0.3 to make the scene quieter in every open terminal

Prompt for your agent

Install backdrop-shell from the repo at https://github.com/thebanri/limoni with the install.sh script, then run backdrop-shell enable -scene <scene> and backdrop-shell opacity <value>. Report the command output and confirm the scene is active in the terminal.

Caveat. The README says the scene costs about half a percent of one core, which is its own measurement and may differ on your machine.
