  • Tell a joke on the LED screen.
  • If your Sense HAT is connected to the internet, you could use a Twitter API library to make it display incoming tweets.
  • Create your own images to display on the LED matrix.
  • Can you alternate between images to create an animation? Check out this Geek Gurl Diaries video for some inspiration.
  • Create an electronic dielike this one. Shaking the Pi triggers the roll of the die.
  • Create a simple graphical thermometer which outputs different colours or patterns depending on the temperature.
  • Write a program that displays an arrow (or other symbol) on screen; this symbol could be used to point to which way is down. This way, astronauts in low gravity always know where the Earth is.
  • Use the accelerometer to sense small movements — this could form part of a game, alarm system, or even an earthquake sensor.
  • Make use of the humidity sensor to detect breath and display a colour depending on the humidity.
