For those who have been living under a WiFi-less rock, TED talks are 20-minute bursts of inspiration delivered in the form of a lecture by an expert in their field, and going under the tagline 'ideas worth spreading'.
Like a global fringe festival, TedX talks are the same, only more prolific. The online TedX library boasts more than 30,000 videos from 130 countries. Our own version, TedXAuckland, takes place tomorrow.
And now, once again, it's Auckland's turn. The fourth TedX to be held in Auckland, this year sees the talk fest moved to a new, larger home at the Victory Convention Centre in Freemans Bay to accommodate the sell-out crowd.
Here are this year's speakers:
