I think Marc is fairly peerless now. Marc's forms are often imitated, but what other designers seldom imitate is his preoccupation with materials and processes. You have to start with an understanding of the material. Often your innovation is just coming up with a new way to use material. In 2013, Ive and Newson collaborated in an auction at Sotheby's for Bono's Product Red. Over forty objects – "each of which we both like ... functional and capable of being made in volume", per Ive; "deeply personal" per Newson – were selected over two years for the auction and show to benefit The Global Fund to Fight AIDS, Tuberculosis and Malaria.
