Sol LeWitt was an artist who worked in many mediums. and was known for his association with the conceptual art and minimalism movements. As you know if you have been reading my posts here, I am interested in generative art. While Sol LeWitt was not a digital artist, he did do some interesting work in algorithmic art: his Wall Drawings . LeWitt believed that the idea behind a work of art, rather than the act of producing it, was the actual art work.
