Beautiful Modeler is a software tool for gestural sculpting using a multi-touch controller such as an iPad. Each finger is used to control a single touch point in the model, with multiple layers working to build up 3D volume. As the controller is connected over the wireless network, it can be moved freely to change the viewing angle of the model.
The finished mesh can be exported as an STL file (thanks to ofxSTL), meaning the sculpted form can be fabricated immediately. In the video above, the positive mesh has been post-processed to create a negative form for fabrication with a plaster-based 3D printer (thanks Zach!).
