Kids' first and favorite jungle gyms are usually an unsuspecting parent. This unique prototype by a young Japanese designer, Atsushi Shiraishi, creates new ways for children to roughhouse with dad or mom. A sturdy, wearable net of soft leather and durable rope lets kids climb all over grown-ups with plenty of support. Part of Shiraishi's final thesis project at Tama Art University, the AthleTitti explores the value of the "low-tech" in an increasingly hi-tech world. Check out the university's website for more images and information on this fascinating conceptual piece.
