This was a bit of an experiment. The idea was to make an hourglass in
which the paint ran down through a narrow opening and spread across
the paper. I first made a relief of paper with the two side triangles a bit
higher. Then I placed the whole upright and ran thin paint from above
over the pre-wetted paper, first the red, then the black.
The end result got a few digital additions. 12,5 x 16 cm.
