You have to do Turbo Mode (Shift+Green Flag) or this will take hours. Literally. Ok, so using some problem solving skills and the Scratch Wiki, I did it! I made some pretty cool pen designs. All of these designs are completely of my own coding and design. I will probably add more later. Here they are: 1-Parabolas 2-Bulging Squares 3-Squares of Liquid 4- Swirl with Diamonds 5- Black Hole 6- Blue and Green Stripes 7- Rainbow Twizzlers 8- Many Bulls Eyes 9- Rainbow Moon 10- Ripple Effect If you can think of better names, please let me know.
