Obviously, it’s pretty two dimensional, and that implementation is very “written in java”. Now there’s all this fun “HTML5” stuff like canvases and the like, so I figure that it’s about time I figure out how they work.
A bit of an odd statement, since the page at the link uses HTML5 Canvas. (There used to be a Java version, but that one is not.)
Maybe they are just talking about aesthetics? Gray boxes with yellow, instead of white, a tasteful muted gray, and HTML5y-light blue?
