A saboteur in the house of art and a comedienne in the house of art theory Lawler has spent three decades documenting the secret life of art. Functioning as a kind of one-woman CSI unit she has photographed pictures and objects in collectors' homes in galleries on the walls of auction houses and off the walls in museum storage.

Pictures deface walls more often than they decorate them.

Urs Fischer specializes in making jaws drop. Cutting giant holes in gallery walls digging a crater in Gavin Brown's gallery floor in 2007 creating amazing hyperrealist wallpaper for a group show at Tony Shafrazi: It all percolates with uncanny destructiveness operatic uncontrollability and barbaric sculptural power.

Information is the oxygen of the modern age. It seeps through the walls topped by barbed wire it wafts across the electrified borders.
