Like a muzzle-loading Minuteman, Jordan Reeves carefully loads each of the barrels of her arm cannon. Power funneled in, she returns any excess sparkles to a secure container, and then mounts her weapon on her left arm. With a knowing grin and an inventor’s glee, Reeves tugs the firing cord, and her five barrels release a cloud of glitter.
Reeves named her device “Project Unicorn,” and at its heart is a 3D-printed prosthetic that sits on her upper arm. Reeves was one of six children invited to a Superhero Cyborg program put on in San Francisco this past winter. Bay area child-centric nonprofit KidMob organized the event, and with the help of 3D designers Autodesk, they had the kids design body modifications for themselves, as superheroes.
From FastCompany:
Reeves isn’t fighting supervillains with her glitter cannons yet, but she’s in touch weekly with a mentor from the project to figure out improvements for the device. And the glitter is just the first stage. Future adaptations may turn the arm-mount into a grocery holder, or a selfie stick, or other functions as needed. There’s a lot of potential for both work and whimsy in 3D printing, and we’re only at the earliest stages of it.
