Sure. 2D and 3D displays in the MASON tarball on the website can be updated every N steps -- it's there in the GUI. On SVN there's a new version of both which have more options. You can update every N steps, or every N seconds, or never, or always. At present this isn't exposed to the developer, but on the SVN version there's a function called shouldUpdate() which handles things and can be overridden -- it's called every step (at least), asking whether a repaint should be requested, and returns true or false. I should get it set up so you can set it up programmatically without having to do an override.
