A little offscreen buffer test with ruby-processing-2.0

A little sketch from the processing discussion board, makes me think that I should revive lazydogs mirror sketch for ruby-processing-2.0, now that would be cool.

attr_reader :pg
def setup
  size(200, 200, P2D)
  @pg = create_graphics(100, 100, P3D)
  smooth(8)
end
def draw
  background 50
  pg.begin_draw
  pg.background 150
  pg.stroke 255
  pg.stroke_weight 3
  pg.translate(50, 50, 0)
  pg.rotate_y 0.45
  pg.no_fill
  pg.box(40)
  pg.end_draw
  image(pg, width / 2 - 50, height / 2 - 50)
end
