Dust3D is a new application unlike any other 3D modeller Ive used. Its free, open source, runs on Mac and Windows, with Linux support possible if you compile it yourself. What makes it unique however is its approach to modelling. Essentially you model by create a series of circles along two axis, which act as loft points for the generated mesh.
