Logitech made a giant wall of 18,400 keyboard LEDs at PAX East

Logitech's "Great Wall of G810s" goes down as one of the most ingenious and impressive spectacles in PAX East history.

At this year's PAX East show, Logitech built a massive colorful wall of out of 18,400 keyboard LEDs to simulate old-school arcade games. The wall used 160 of Logitech's new G810 RGB mechanical keyboards, and was made possible thanks to custom laser-etched keycaps to make every key simulate a colored pixel. The huge LED wall drew lots of attention at the show, and reportedly took six months of planning to orchestrate.

"I'm a dork, I'm a nerd, I grew up playing Pac Man, Space Invaders, Asteroids...so I thought 'how cool would it be if we built a huge wall out of our keyboards and we programmed a video game on it," Logitech's Vice President and General Manager Ujesh Desai told Gamers Nexus.
