cross-platform 3D application for free. At the time, this was a revolutionary concept as most commercial 3D applications cost thousands of dollars. NaN hoped to bring professional level 3D modeling and tools within the reach of the general computing public. NaN’s business model involved providing commercial products and services around Blender. In 1999 NaN attended its first SIGGRAPH conference in an NaN with new investor funding and a smaller company in April 2001. Six months later NaN’s first commercial software product, Blender Publisher was launched. This product was targeted at the emerging market
