Yep took the challenge and modified the project by JSO: - added a color pen - color is set to the xpos - there's a slider to control the size of the pen Click the green flag and it clears the previous drawing This project lets you record and play back movements of the mouse. It uses lists, a new feature in Scratch 1.3. The lists store x and y positions of the mouse. Can you modify this project to make it record and play back a drawing? What else can you record and play back using lists? Thanks to JSO for creating this project!
