The frame% object has a fullscreen method that makes it fullscreen (on OS X, this makes a new desktop): http://docs.racket-lang.org/gui/frame_.html?q=frame%25#%28meth._%28%28%28lib._mred%2Fmain..rkt%29._frame~25%29._fullscreen%29%29 You could hack big-bang to have it call that. In lux, there's a #:start-fullscreen? argument that calls this when it makes the window. > To start with, I'm making simple rectangular grid games, which are very > easily scalable.
