By virture of the Unicorn HAT being a HAT(!), and hence using the Raspberry Pi's GPIO pins, all of these examples must be run with sudo, for example

sudo ./clock.py

or

sudo python clock.py    

Note: If you're using a Unicorn pHAT make sure you specify in your code, like so:

import unicornhat
unicornhat.set_layout(unicornhat.PHAT)

Uses graphics.py and shows how you can, but probably shouldn't, display an analogue clock on Unicorn HAT!

Multi-effect demo; twisty swirly goodness, roto-zooming checker board, weeee waaaah, rainbow search spotlights and zoom tunnel

Knock, knock, Neo.

Demonstrates the use of colorsys to animate through colour hues.

Blinks a rainbow spot light on and off. Change fwhm to make the spot more/less focused (smaller numbers = more focused/larger numbers = less focused).

Blinks random yellow-orange-red LEDs.

Random multi-coloured sparkles.

Use your web browser to pixel paint onto Unicorn HAT.

Requirements:

sudo pip install flask

Shows how you can open and display a PNG image file, great for sprite animations.

Requirements:

sudo pip install pillow

Sets each pixel in turn and updates the display.
