A while back I wrote this post about a way to process pictures pictures for a Pop-Art like look.
I guess nobody ever tried this because it’s pretty complicated and I also wanted to just give it a shot so I cobbled together this thing

Usage is pretty simple, drag a picture into the page 

and once it’s loaded press Pop!

et voilà! you got yourself a cool picture
If you like you can simply save the picture by right-clicking it.
You can change the color scheme, invert the picture, go back to the original picture or load a new picture.
