Quickly drawing grids of rectangles, and updating their colors with VisPy

VisPy is a Python library for interactive scientific visualization that is designed to be fast, scalable, and easy to use. Esologic talks about drawing grids of rectangles, and updating their colors all quickly with VisPy:

Absolutely insane, achieving that kind of performance in python is amazing to say the least. This demo in particular seems like it would be more likely to come from a pygame application at the least, but looks more like it would be a Unity project.

The VisPy project is massive, but luckily, there is a set of really good examples included in the repo. Reminds me of the Arduino standard library in this way. After through all of running these, I didn’t find exactly what I was looking for.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
