Showcase Examples

These examples¹ are the executable .sevgi files from showcase/srv, not copies written for the site. The test suite runs each file and compares its output. Open the Ruby panel for the script and the SVG panel for the result. Most are small enough to read in one sitting, though a few keep enough detail to show how a real drawing comes together.
