HP has announced the launch of DesignByMany, an online community which invites designers to come up with solutions for “Building for the Greater Good.” One challenge: Create a parametric version of Buckminster Fuller’s Dymaxion House for the chance to win an HP Designjet 111 Printer. HP has other interesting offerings too: Consider the HP ePrint & Share plug-in for the Designjet, which lets users of AutoCAD create print-ready files with just one click.
