In Stanislav Grof's (pictured below) book "When the Impossible Happens" there's a chapter about Luiz Antonio Gasparetto, a psychologist from Brazil who can go into trance and paint in the style of a wide range of dead famous painters (Monet, Picasso, Rembrandt, da Vinci, Modigliani, Manet, van Gogh, Gauguin, etc). He doesn't just paint exact replicas of existing paintings but "new motifs rendered in easily recognizable styles of individual artists".

Dr. Grof describes how they actually turned all the lights off except for one little red light over the paper (red so that he couldn't distinguish color)...he would at times paint with two hands two different paintings at the same time and even did one upside down under the table with his right foot.

Loyd Auerbach who was present at one of the demonstrations writes: "The climax of the demonstration was when he did four paintings at once: one with each hand, one with each bare foot (these being done under the table at which he was seated), while his eyes were closed and he carried on a conversation. Each of the four paintings, by the way, was supposedly by a different one of the spirit artists (and they were, in fact, in four distinct styles that an art expert there related to the named artists)."
