Visionaries exploring sight and vision.
Add to list
I listen to color
9 minutes 35 seconds
Artist Neil Harbisson was born completely color blind, but these days a device attached to his head turns color into audible frequencies. Instead of seeing a world in grayscale, Harbisson can hear a symphony of color -- and yes, even listen to faces and paintings.
Looking past limits
19 minutes 17 seconds
Activist Caroline Casey tells the story of her extraordinary life, starting with a revelation (no spoilers). In a talk that challenges perceptions, Casey asks us all to move beyond the limits we may think we have.
Optical illusions show how we see
16 minutes 30 seconds
Beau Lotto's color games puzzle your vision, but they also spotlight what you can't normally see: how your brain works. This fun, first-hand look at your own versatile sense of sight reveals how evolution tints your perception of what's really out there.
The way we think about charity is dead wrong
18 minutes 54 seconds
Activist and fundraiser Dan Pallotta calls out the double standard that drives our broken relationship to charities. Too many nonprofits, he says, are rewarded for how little they spend -- not for what they get done. Instead of equating frugality with morality, he asks us to start rewarding charities for their big goals and big accomplishments (even if that comes with big expenses). In this bold talk, he says: Let's change the way we think about changing the world.
Exposing the invisible
13 minutes 18 seconds
Nick Veasey shows outsized X-ray images that reveal the otherworldly inner workings of familiar objects -- from the geometry of a wildflower to the anatomy of a Boeing 747. Producing these photos is dangerous and painstaking, but the reward is a superpower: looking at what the human eye can't see.
