This Lego MOC of the Atari Pong system is spot on. From the fake wood cabinet, to the joysticks everything has been carefully thought through. Speaking of which, those joysticks are genius; using Lego tires worked well. Here the retro styling works well with Lego. The system currently doesn’t work, which like most Atari Pong systems is accurate.
