San Francisco Women Artists presents “The Art of Bill Ham”

SFWA presents “The Art of Bill Ham” – known as the originator of the 60’s psychedelic light show. Join us Thursday, June 8 for the Opening RECEPTION. 647 Irving St. Bill is currently featured at the de Young Museum. BILL HAM In Mr. Ham’s own words, his acrylic paintings on canvas follow in the lineage of ‘Abstract Expressionism,’ with a nod to Jackson Pollock. And, while referencing this post World War II art movement, Bill has gone farther in development of techniques, defining his paintings as ‘Gestural Abstraction.’ Importantly, the artist applies painterly gestures while the canvas is positioned on a low flat surface or flooring. Mr. Ham works from all sides as he develops the imagery from his overhead viewpoint and position. As a result, the client can choose and change the viewpoint of their purchased artwork. Top, bottom, left, or right are no longer applicable to the position and installation of his art. The options for placement of his paintings are myriad; as an example, please refer to his “Four Square Paintings” information sheet. Bill passionately expresses camaraderie with the San Francisco art scene, artists, and local creatives, with whom he identifies. The San Francisco Women Artists Gallery is honored to celebrate the 50th Anniversary of the Summer of Love with the special Artist Salon exhibition, ‘The Art of Bill Ham.”


1) For 4 square shaped paintings there are 3 different symmetrical rectangle layouts. 

2) For each of the layouts there are 6144 possible combinations.
 The calculations for each layout are the same.
 There are 4 possible paintings for the first position.
 It can be placed in 4 directions.
 There are 3 possible paintings for the second position.
 It can be placed in 4 directions.
 There are 2 possible paintings for the third position.
 It can be placed in 4 directions.
 There is 1 possible painting for the last position.
 It can be placed in 4 directions.
 The calculation is to multiply all possible combinations.
 4 X 4 X 3 X 4 X 2 X 4 X 1 X 4 = 6,144

3) The total number of possible paintings for 4 rectangle paintings is: 18,432.
The calculation is the number of layouts multiplied by the number of possible combinations per layout.
4 X 6,144 = 18,432
