When the NES was popular, TVs were still relatively small, usually measuring somewhere in the 20-inch range. Regardless, light gun games like Duck Hunt that required the user to precisely hit a certain area of the screen kept gamers entertained for hours and hours.
Though screens have increased in size, YouTuber Dan Hoover had much bigger plans, and made a version of Duck Hunt on a gymnasium wall using 20 LEDs to signify flying birds, along with corresponding laser sensors.
To play, as lights on each of the 20 painted ducks are switched on by the control system, the player must shoot it with a generic light gun modded with a laser inside, reminiscent of a laser version of whack-a-mole.
The setup uses an Arduino Mega to handle the I/O, along with a Raspberry Pi 3 and an Apache web server to handle game timing and audio playback. User interface is via a web application, so it can be controlled by a smartphone, or a laptop as seen in the video here.
