This Redditor based in London is able to draw Mario on a web app that controls an LED device. The filmer, who goes by @neyth_makes, draws a scene from the "Super Mario" franchise on his computer which is then replicated on a board full of LED pixels. They said: "This project uses a small computer called a Raspberry Pi to control a 64x64 screen composed of LEDs. "The Raspberry Pi hosts a website which can be accessed from any device with a browser, here I'm using my MacBook. The browser runs a web app that allows you to control the colour of each of the 64x64 LED pixels similar to a standard paint application." This footage was filmed on March 21.
