It is sometimes necessary to use paint with objects and other material in order to create a certain atmosphere, to convey an idea, to evoke a feeling.

One sometimes needs to create multilayered, multifaceted images, aggressively exhibiting the rawness of something other, an interference, even an unpleasant intrusion.
