Whothm
This is a web-based interpreter for the Whothm drawing language.
Whothm is a simple language for describing infinite two-colour bitmapped graphics.
It is described fully in the documentation in the Whothm distribution.
Technically, this installation is whothm.lua (an implementation
of Whothm in Lua) running under Fengari
(an implementation of the Lua VM in JavaScript)
running in an HTML5 document.
Instructions:
Click "Run" to run the program. The result is displayed in
the canvas on the right.
Syntax errors should result in an error message in the status bar,
but might not in all cases. In these cases, consulting your browser's
console, 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.
