I contributed five layers to https://www.105collective.uk/ 's Async piece, "More Than Glass", which was auctioned very successfully on 24/10/20 https://async.art/art/layer/0xb6dae651468e9593e4581705a09c10a76ac1e0c8-781 . "The @ Clock" started life as a physical piece. 12 versions of it appeared in "More Than Glass"; there are 60 versions here.
