This project allows you to move the Sprite and then save the motion as a SVG image which can then be cut out on the laser cutter. A SVG describes an image as one or more polylines, each of which is defined by a collection of points. 1. Remix this project. (You'll need to be logged in.) 2. Add blocks to the "Draw SVG" hat block. Start a new line, then move the sprite around and add points, and then end the line. Note that if you want a closed shape, you'll need to add the initial point again at the end. 3. Run the script. When it looks the way you want, follow the on-screen instructions to download the SVG.
