Need Idea for school project

Guys, do you have any cool or creative ideas to share?? This is the codes that can draw your face with random lines. Simple Hardware + Software ( arduino board) maybe?? HELP

that's funny you pasted the code I showed you and started a new thread. don't.

did you notice that the sketch belongs to 2 collections showing examples?

did you browse the 2 collections?

what sensors do you have on the arduino also for movement or pitch/yaw/roll?

an idea could be to enroll 2 colorful triangles that get smaller and more (split up) over time and after 40 seconds stay put.
