Tactus Technologies has released a new modeling tool they describe as a ‘tool based free-form modeler’.

Protean is a new software program developed to address the need for creating true 3D free form objects in a single, easy to use package. It uses a physical clay paradigm and is exceptionally suited for designing organic as well as inorganic models, from toys to knee joints. It is not a mechanical CAD system, yet you can make exceptional 3D prints for rapid viewing your design using Protean’s export facilities.

They have a free demo online so that you can try it out.
