 So think about how we build things. It's pretty complicated, right? Involving an assembly line of robots or actors to build something. That's pretty cool. But what if you had one robot, and that robot was a screen? That's basically what MIT's done with its Kinetic Blocks project. Okay, so it's not exactly like the screens we use in our phones or TVs. It's actually what MIT calls a pin-based shape display, which is an array of computerized pins that move in physical space according to spatial data. That data is fed in by a Kinect camera hovering above it, allowing it to create 3D representations. Basically what that means is if a Kinect sees a hand, it creates a hand in 3D. It's pretty cool, and MIT already pulled that off a few years back with its InForm project. But with Kinetic Blocks, MIT has ratcheted up what the display can do to make it capable of building stuff. If it's fed the right data, it can manipulate blocks, rotating them and even stacking them on top of each other. Things get extra cool when it uses magnetic blocks, which leads to even more complex structures. So imagine building more complicated things this way. What about cars? Or phones? Yeah, we're not there yet. But MIT's thinking a lot about this with an idea called Radical Atoms. Basically what that means is they're envisioning a world where all the data can be manipulated in the physical world. It's a long way off, but it's a world I'd like to live in.
