Wonderful, whimsical illustrations by Ann Nowacka — TEDxKraków’s resident designer. "Drawing is my primary way of thinking," Ann says. "Before I can speak my mind, I see pictures … I draw the magical world that surrounds us … I continue to look for beauty around me."

Ann worked closely with the TEDxKraków to develop the event’s visual identity. Learn more about the event housed in one of Poland’s oldest cities at their website, featuring some of Ann’s designs»

At TEDxYouth@Manchester, genetics researcher Dan Davis introduces the audience to compatibility genes — key players in our immune system’s functioning, and the reason why it’s so difficult to transplant organs from person to person: one’s compatibility genes must match another’s for a transplant to take.

Prosthetic limbs that match your body … and your style:  Industrial designer Scott Summit uses 3D printing technology to create individualized artificial limbs that users can choose and personalize to fit their unique style.

In a talk at TEDxCambridge, Summit explains how this process not only gives users autonomy over the aesthetics of their prosthetics, but also makes for artificial limbs that factor in the quirks, curves, and uniqueness of a user’s body, eliminating the need for prosthetic-wearers to hack their artificial limbs — with socks, bubble wrap, even duct tape — to feel comfortable.
