He's rediscovered Pointilism. MSRenoir. Hats off to his dedication in doing art that way.
Amazing how his need to 'paint' found a way. Reeeespect!
It mentioned in that vid that he designed Lasko font, a very fine copperplate style.
His forte was finely detailed art work and calligraphy so he is geared to that style, and has a talent for patience. It wouldn't work for most of us.
