What’s up in the world of product design? Here are stories from the past month we think you’ll like:
Building Blocks for Engineers
LEGO builds toys that are “primarily about architecture and design,” wrote Nerdist recently. K’nex, on the other hand, “is about engineering.” K’nex started as a system of rods and connectors, but soon grew to add pulley’s and gears so kids could build vehicles, aircraft, and roller coasters.
Perhaps nobody has embraced that thinking more than YouTuber Shadowman. Not long ago, he posted a video of his Citadel—a massive structure that direct balls along different pathways—all made with K’nex pieces. He’s been working on it for 3 years.
