Some of my own examples for the Raspberry Pi Sense HAT.
This might become a bit of a dumping ground for short projects and sample code, but I'll try to keep it as tidy as possible.
Firework.py is a script which allows you to have your very own firework display using the Raspberry Pi Sense HAT's LED display grid. This code could easily be adapted to suit other LED displays (I'd love to see it on a Ubercorn hat!). See ModMyPi's tutorial which lives on their blog here.
rainbowscroll.py is a script which creates a beautiful diagonally scrolling rainbow on the Sense Hat. Mainly inspired by Mag Pi 93's idea of making a rainbow on the Pi, except I used this to remind me of modular arithmetic and using ranges in loops.
