So you're interested in 3D printing, but how would you go about creating things to print? Leonar3Do offers a complete package that's supposed to get you up and sculpting 3D projects in around 20 minutes.
To use Leonar3Do's 3D mouse, you move it around through the air--it has several simple buttons that you use to control the mouse's functions as you interact with the object you're creating.
The inventor claims that the learning curve for use of the mouse is relatively short--according to university trials, the average user needs about 20 minutes to get up and running with the Leonar3Do program.
