If you have no idea what this project even is, try refreshing... This works best if you are using a Chromium-based browser, such as Vivaldi (works best!!), Edge, Chrome, Opera, etc. However, this does work on Gecko and WebKit, so don't get discouraged.
This takes a tutorial from https://scratch.mit.edu/projects/1304446771/ And i learned about this from @blessingj100 I feel like this has more potential, and i will experiment with this in the future.
