Beautiful Handcuffs," but Interactive Fabrication's "Beautiful Modeler" iPad app is probably a bit more useful (though not as useful with the ladies). The concept is to use the iPad's multitouch screen as an input for multi-finger 3D modeling on a computer, while the tablet's tilt sense lets you navigate around the object. Sure, it's not as slick or precise as, say, the Axsotic 3D mouse, but it also looks a whole lot more "tangible." Unfortunately, the app is currently unavailable on the App Store, and we have no idea if it's ever headed for a computer near you -- Interactive Fabrication is all about the high concept stuff, leaving the execution to individuals -- but there's some freely available GPL-licensed source code if you want to take a crack at compiling and making a real product out of this. Check out a video of the sculpting in action after the break.
