This takes a long time, please by patient. Simply replace the background with your own and press the green flag. Press space to stop the render. I'll try to add more render modes. (I suggest you use string.) SCompact takes a really long time to render. If you have a remixed render mode I'll see if I can add it. Use Turbo Mode. Pho String is Phosphorus compatible. Important: Rename your image to "Image" or it will not work. This is the fourth test for this. It is the only successful one. This took about 2 weeks total on all the tests.
