I have not kept track of most of my umcompleted projects (and many of the completed ones - ) I believe this is quite alright - Most of what has never been done was either to boring, inconvenient, incorrect, or whatever - no regrets. Some projects made have, some not (both ok), some could be obsolete, some gained pertinancy -
In 1966 a do, with the Ecart group, we planned large underwater drawings on the bed of the Lake Geneva - We ended just gazing at the Lake, imaging them. They wouldn't have been visable anyhow! we tyed floating sculptures on the river Rhône. They, the models sunk.
In 1974, I was asked, amoung others to design a piece of Military Baracks in Switzerland. My piece was rejected. To be installed in the hall the piece consisted of black walls painting wiht board painting, and covered displays of available chalks for people to use - Anyways, I was just out of prison for refusing to do my military service - what....here guys to with a ....in their walls of a pacifist activist?!
For a lighting project around geneva most of it under earth, I suggested to plant trees in give above (like along the main roads before) - So, that how it goes - last drawings, next page, is a garden. Hell of a work isnt it - Or?
