/// This macro runs three "games" that each nicely illustrate the graphics capabilities of ROOT.
/// Thanks to the clever usage of TTimer objects it looks like they are all executing in parallel (emulation of
/// multi-threading). It uses the small classes generated in $ROOTSYS/test/Hello, Aclock, Tetris
