This project uses sine (a trigonometric function) to s moothly move a group of balls, adjust the shading of those balls, adjust the transparency of the stage, and play a mystical song. Hold Space to display a slider, which you can use to slightly adjust the speed of it all. See how satisfying it is?!
If Turbo Mode is enabled, there will also be an Intense Flashing option, which you can click to enable, but you should never enable it if you have photosensitive epilepsy. This project is partially inspired by a project created by @pink_daffodil22: https://scratch.mit.edu/projects/1217799582 and by this YouTube video: https://www.youtube.com/watch?v=OMq9he-5HUU
