To celebrate Global Accessibility Awareness Day, Stevie Wonder performed a special concert at Apple’s One Infinite Loop headquarters on Thursday.

Apple CEO Tim Cook took to Twitter earlier today to thank the singer.

Thursday was the sixth Global Accessibility Awareness Day. The purpose of GAAD is to inform and educate about digital access and inclusion for people with different disabilities.

Earlier in the week, Apple released a number of videos showing how the accessibility features are used by different people.

An example below, “Designed for Andrea D.” shows how the Apple Watch is used to record wheelchair-specific workouts.

Cook also sat down with three advocates to discuss the importance of accessibility.
