Use TURBO mode to see the pattern. (Press the <Shift> key and click the Green Flag for TURBO mode). Credit to Scratch-Minion Whipped this up in, maybe less than 20 minutes. Don't know exactly what I was trying to achieve here, because I'm not very good when it comes to formulas regarding the pen colour. So I just fiddled around at random, adding completely random things to the formula and deciding whether it looked good. The best part is where I had this crazy idea to replace the original "set pen colour" block with the one that has an eyedropper. If you put a number in the eyedropper one, the eyedropper will use the number as a hexadecimal colour.
