Leonar3Do offers an easy design program for your 3D printer (photos)

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.

To view the object you're sculpting in 3D, you need 3D glasses, which are included in the complete set.

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.

The Leonar3Do package retails for about $1,350 and includes everything you see here.

You can push and prod your virtual clay ball until it resembles the character you've got in mind.

You can start with any number of shapes; here we see the sphere.

This fellow is playing with a skull-shaped work in progress.

We may start seeing a lot of characters designed in Leonar3Do if this product takes off.

Once you've finalized a piece it can be printed--provided you have a makerbot or other 3D printer. These are examples of work done using Leonar3Do.

As you can imagine, gaming applications are another area of use.
