Check out Luyang’s work at his website or in this Youtube playlist. 

To make these animations, Luyang uses Processing, a 20-year-old language that started out as a visual way to teach programming but evolved into a professional development tool. 

Logitech selected Luyang as one of the ambassadors to show off what you can do with their MX Keys S Combo. 

Shout out to George Profenza for dropping a top answer on Position of a vector in coordinate system (Processing/p5.js).
