Tried a little experiment walking home today : looked at things as if I were in a Bruegel painting. I saw the firm prehistoric charcoal outline marking the integrity of human figures; the fine detail in the distance; the feeling for trees. Missed some of the warm colors. (Used to do this kind of thing after Fellini movies, back in high school.) Some little kids yelled at me from a 2nd-floor window, trying to get my attention : that was Bruegel too.

Could be done with all kinds of artists, I guess. if you do Bosch or Francis Bacon, though, you might want to bring a friend for company.
