Industrial designer Marc Newson has been announced as one of the speakers at the annual ideas festival TEDxSydney.

One of the world’s most influential industrial designers, Marc has collaborated with Caroma on a collection that includes baths, mixer taps, showers, concealed toilet suites, basins and urinals.

Marc will participate in a Q&A session on stage with curator and television producer Julian Morrow.

The TEDx series is a spinoff of the international TED Talks, but will have a local focus.

TEDxSydney is on May 4 at the Sydney Opera House and people can apply to be part of the audience or watch online.
