The pencil-stroke is like cutting into the heart. - Günter Brus

In simple terms: art has not been a public nuisance for quite a while now. either the people have become well-behaved or the perpetrators of nuisances have become tired.

I covered the walls of both basement rooms with Milino,a cheap substitute for canvas,stretched string backwards and forwards across the rooms and attached widths of packing-paper to them,so that they reached down to the floor and as far as the walls that I wanted to paint. I wanted to create a labyrinth which would somehow help to prevent a compositional idea from establishing itself all too quickly. I had the idea of working on all the walls pretty well at the same time,as if they were one large painting completely surrounding me. By constantly wandering in the labyrinth I sought to realise a form of “de-composition”.

Being covered in white paint ,you demonstrate behaviour intended to create a public nuisance,which did in fact cause offence to members of the public ,and created a breach of the peace and public order.
