TED Fellow Alicia Eggert takes us on a visual tour of her work -- from a giant sculpture on an uninhabited island in Maine to an installation that inflates only when people hold hands to complete an electric current. Her work explores the power of art to inspire wonder and foster hope in dark times. As she puts it: "A brighter, more sustainable, more equitable future depends first on our ability to imagine it."

Art's capacity to evoke wonder and foster hope is embodied in a sculpture spelling 'FOREVER', transforming with the fog's ebb and flow.

A vivid recounting of apartheid-era South Africa underscores the influential power of social movements and collective vision for change.

Engaging public art installations, like an inflatable sculpture activated by human touch, illustrate the tangible magic of collaboration.
