While I'm not sure how huge 3D printing is going to be, I'm somewhat more sure writing in 3D will be pretty huge. Watch this jaw-dropping video:
It's a Kickstarter project, and when I first saw it last night, it had raised about $10,000. Less than 12 hours later, nearly $200,000 had been pledged. So guess I'm not the only one jazzed about the idea of writing 3D into reality.
