The game inside the glass: pick Asteroids, Doom or Pong at the top rightLow tapered plinth with one controller shelf, on the right: a ball-top stick and two buttonsThe Prism glass at arcade scale: a long booth where the glass is nearly all of it, holding a matrix of 27 × 17 × 17 light points. Pick a game at the top right, tap the figure, and play from the keyboard or with the control pad in front of the booth: drag the stick to steer and tilt, and press FIRE, BOOST and BRAKE. The booth is drawn in two-point perspective: drag across it to turn the view, and pinch or scroll to zoom. Asteroids: left and right steer, up or W boosts, down or S brakes, Q and E tilt the nose, space shoots one ball at a time; you bounce off boulders and walls, and knocks wear down the health bar slowly. Doom: you are a marine on one floor with solid pillars for cover; left and right turn, up and down walk, space shoots the things that walk at you. Pong: the ball runs the length of the field; left, right, up and down move your orange paddle on the near wall, against the blue one.
