The Gobo Lab is a browser-based virtual light lab. It lets you experiment with gobos and textures and lighting direction. There are nine different lighting positions available. Each can hold one of ten different gobo templates. Each can be set at a different brightness. Two actors stand on a small stage surrounded by simple scenery. This is an excellent tool for demonstrating the principles of direction and texture for light either for an individual, or in a classroom. Test on Safari, Chrome, Firefox, and Opera. Sorry, it will not run on Internet Edge/Explorer.
