Dan Mafe's paintings are wonderful! I can look and look at them, and still not get tired of looking.

Earlier paintings are more geometric, but always with a layered and playful surface that rewards close viewing as well as looking from a distance - and many of these works are large!
and some works consisted of more than one canvas (two large and one smaller canvas in this image below).
and a detail - where the circles mesh across from one canvas to the next:
Those paintings were made on the horizontal and layer after layer of the paint allowed to pool. More recent works are obviously painted while vertical, at least in part, but still are incredibly layered and complex as a spatial surface.
