All the interactive graphical animations are written in pure JavaScript using the HTML5 canvas element. If you encounter some bugs (or have some suggestions) let me know at cp@charlespetzold.com. But if you encounter serious problems with the graphics, your web browser might be at fault. (Perhaps it's time to move on from Internet Explorer.)
