Whothm is a simple language for describing infinite two-colour bitmapped graphics. This exhibit contains a Java applet which implements Whothm, and lets you interactive try out Whothm programs online. The implementation is only an approximation; only a small portion of the infinite drawing (a couple of hundred iterations) is rendered. The rest is left up to your imagination.
Quick Start Guide
Whothm is a simple language for describing infinite shapes. It is described fully in the documentation in the Whothm distribution.
Click "Run" or press Alt+R to run the program. The result is displayed in the canvas on the right. Page Up and Page Down can be used to zoom in and out of the canvas.
Syntax errors often result in an error message in the status bar, but might not in all cases. In these cases, consulting your browser's Java console, if it has one, might elucidate the cause of the error. Or it might not.
Obviously, this implementation does not support generating or displaying the entire infinite drawing. In fact, it only runs the loop for a couple of hundred iterations. The full shape is left up to your imagination.
