Yep. You can alter textures. Not very useful. Drag the circles around. There's a custom block that you can use, (with credit) inside the project. The first 2 values in the block are the dimensions of the texture, ("xx", and "yy") and the rest are the coordinates for the 4 points. (Except the final value, color alteration "lol") Make sure you load the texture into the list "pic", if you use it.
Press space for a surprise. It was an easy project, took about an hour. (I tried a few months ago but couldn't figure out the mid distance formulas correctly)
