Really simple code but ended up quite good! Filter is done by me on just scratch. The code is literally just 5 blocks.
Couldn't think of anything to do for a Christmas project so I just did this. I might make more filters since this was quite fun to make! EDIT- In recent times I've noticed a bug, and this filter doesn't work if you have any safe cam/ anti hacking software-SOMETIMES. If it doesn't, just open the software and allow the camera to access scratch.mit.edu and you'll be good!
