If you go to a casion, look out for WMS slot machines, specifically this one (Goldfish (the new one, not the old machine)) I played this in Atlantic City at the Trump Taj Mahal downstairs next to the noodle bar and they use a transparent LCD over their spinning reels. Pretty cool stuff.
Are those actual physical spinning wheels? On the video you can't really tell that it's not just one giant screen, I bet the effect is cool AFK though.
