Not a very complicated project this time. This was just a phenomenon I came across while experimenting with a checkerboard pattern generator. Basically, what you do is create an image by layering differently sized checkerboards on top of each other. You can control their size with the slider in bottom-right corner. If you want to clear the image, press the space bar (just make sure the slider isn't selected). If you want to save your creations, you can rightclick the scene and click on 'Save image as'. I highly recommend using Turbo Mode to avoid having to wait too long for the pattern to load.
