Hello! This is just a little sandbox I made where you can play around with scratch effects. At any point, you can press the enter key, which will pause the simulation. Press enter again to unpause. Press space to get a savecode, than press the upload button to load.
The effects work because although it looks like an ordinary box, it actually has a larger invisible box. This tweeks the shape to make the effects work in weird ways. One of my personal favorite codes: 0|2|1|10|0|1|0|0|. Another fun thing is to make it slightly pixelated, than turn off the effect
