Many of the dense fractals I have been exploring lately naturally live on a two-dimensional sphere. A while ago, I started displaying them as full spherical panoramas using a Java applet ( see this blog post ). With all the recent problems with Java, and browsers strongly discouraging people to launch unsigned Java applets, I had to find another way of displaying them. Luckily, Matthew Petroff wrote a very nice WebGL applet for this purpose, Pannellum , which is now used throughout my website. See three examples of spherical panoramas here . And the full collection of images coming with spherical panoramas can be found here !
