Alright, this is pretty neat. We suspect the responsible parties won't be mentioning the likes of Lego and Minecraft in its press material, so we'll have to do it in this post. The conceit here is pretty simple: Blokify is an iOS app with a 3D environment where you can build models with cubes -- things like castles, spacecrafts and pirate ships. And once you're done, you can print the models at home or via the cloud through 3D Systems' Cubify service (using the company's ProJet 660PRo). The iPhone/iPad app is free, but additional kits and parts are available as an in-app purchase. Professional printing will be as well, with pricing based on the size of the set you build. You can grab the download in the App Store link below. We played around with it a bit earlier today -- it's fun and dynamic, even if we aren't quite ready to drop the extra cash needed to make our tiny castle a reality.
