Matt and Rebecca walk, and then drive, while they talk about unfinished artworks of different kinds, including Le Crocrodrome de Zig & Puce by Niki de Saint Phalle and Jean Tinguely from 1977, and Anthony McCall’s failed artwork, Column, from 2012. n.b Matt says McCall received £100,000 of funding, but the true figure was around £535,000.
