World-famous designer, educator, and play advocate Cas Holman joins Zibby to discuss her radiant, provocative, and essential new book, PLAYFUL: How Play Shifts Our Thinking, Inspires Connection, and Sparks Creativity. Cas—best known for her Netflix Abstract episode and her imaginative creations like Rigamajig—shares how decades of designing for children led her to explore why adults need play just as much. She and Zibby discuss the “three conditions” for rediscovering play, how play fosters creativity and connection, and why letting go of rules and expectations can help us live more authentically.
