I've ported my JavaScript pie menu code to OpenLaszlo, and rewritten it to take advantage of Laszlo features like Flash graphics and animation, constraints, events, prototype customization, and XML data binding.

I'm using the Laszlo pie menus in the Sims Content Catalog, and the von Neumann 29 State Cellular Automata, and other projects.
