this is pop
This Last Supper was created by 5 artists at Toronto based Cube Works, using over 4000 Rubiks cubes (check out some of their other Warhol homage pieces including Marilyn, Mao and Campbell's soup).
I mention Warhol homage but the Cube works style is probably more akin to Roy Lichtenstein's Benday dots appropriation, eh art anoraks?
Though, as Jeremy from Popped culture rightly asks;
'Do you think they arranged the sides by hand, or just removed the blocks and/or stickers to arrange them the way they wanted?'
