Tomas's DJ - "Exploration of the inner Self"

M&M and I are going to a gallery. As we get there, we can see many people painting on the canvass. those are not any concrete paintings, ore of a modern, geometrical shapes. Its a large, complex building. Those people seem to be from the street, random people just being creative. It seems like a class. Then, some lady comes in. She is a professor. She advises these people how to paint it better and how much it can be sold for.
Then I see a girl painting some squares. The professor comes to her and tells her to paint in lines from the right top corner to the opposite one. This will make it look dynamic. She starts to pint in to the girl's painting and totally changes/destroys it. The girl is just watching it, all upset. The girls pulls out some money and gives it to the professor. it is £40 or £55 per hour. The girl was there for about 3 hours. She tells us that she comes very often.
