Josef Prusa was never satisfied with things as they are. Fascinated with the way things work, Josef would find better ways on how he could improve it and in several cases, totally changed to a brand new use than what it was originally designed for. At the age of 18 he already published his own chapter in book by O'reilly called iPhone hacks. Since then he makes more and more uses for stuff. In 2010 his main focus of work has shifted to developing Open Source 3D printer project called RepRap (http://reprap.org) and Open Source Hardware generally.
In the spirit of ideas worth spreading, TED has created a program called TEDx. TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. Our event is called TEDxVienna, where x = independently organized TED event. At our TEDxVienna event, TEDTalks video and live speakers will combine to spark deep discussion and connection in a small group. The TED Conference provides general guidance for the TEDx program, but individual TEDx events, including ours, are self-organized.
