These are paintings done by Ruth Andre, http://ruthandre.com/, and featured on her "A Painting Day" blog. http://apaintingday.blogspot.com/ They were done from the first challenge post here. She has done one more that I will post when I get the jpeg of it.
I have seen some that were also done of these images, by Kim Santini and will post when I get them. Anyone else who has done a piece from any of the images on this blog...let me know and I will post them and a link to your website too.
