If you’re as huge a Portal fan (WHEN IS PORTAL 3 COMING OUT?!) like myself, this requires no introduction. Penn State University student Kevin Swanson with his professor’s support just decided to go ahead and build one for his final Advanced Mechatronics project. The video shows it working pretty much how I envision it to and the final version will ideally look exactly like it’s in-game counterpart.

Thankfully it’s only loaded with Nerf darts!
