README

Adds an interactive, animated unicorn that gallops across the TYPO3 backend — complete with sparkle trails, physics-based jumping, and a handful of easter eggs.

Features

Unicorn runs and bounces across the bottom of the TYPO3 backend
Physics-based jumping with adjustable jump height
Sparkle trail of stars, hearts and butterflies following the unicorn
Upside-down mode: unicorn flips and runs across the top of the screen
Star shower easter egg
Fully keyboard-driven — no clicks required
Works across all TYPO3 backend iframes
No configuration, no database records — install and it just works

Installation

composer require luisasofie/unicorn
vendor/bin/typo3 extension:activate unicorn

Or install and activate via the TYPO3 Extension Manager.

Keyboard controls

Key	Action
`Ctrl / Cmd + U`	Summon / dismiss the unicorn
`Ctrl / Cmd + .`	Pause / resume
`Arrow Up`	Jump — each press also raises the jump height
`Arrow Up` × 2 (quickly)	Star shower easter egg
`Arrow Down`	Toggle upside-down mode (runs on the ceiling)
`Arrow Left / Right`	Slow down / speed up

Note: the arrow keys are relative to the unicorn's direction of travel. The key matching the current direction accelerates, the opposite one slows down — so while the unicorn runs leftwards, Arrow Left is the accelerator.

Documentation

The full documentation lives in Documentation/ and covers the controls, the easter eggs and how the extension hooks into the backend.
