Except for the volcano itself, everything is rendered with pen. It's not really that hard but I thought the design and concept would be interesting, so I made this project. The above notes are Nova's. Push space bar to cycle through scenes.
My thanks to Nova for the code, which I am trying to understand. Thanks also to ijnelson137 for sharing this project with me. The only things I did to the project were to add photos for costumes for one of the sprites. The photos are mine and were taken at the crater outside of Winslow, Arizona; the Grand Canyon, and Canyon de Chelly National Monument.
