Check out these artworks by IndieTheIntrovert, including the one pictured below, which is titled “Escher’s Other Dogs.” FYI: M. C. Escher, one of the major inspirations of Douglas Hofstadter’s 1979 book Gödel, Escher, Bach, was a Dutch graphic artist who made mathematically-inspired art. Among other things, his work features mathematical objects and operations including “impossible objects” and explorations of infinity, and his work has appeared on the covers of many books and record albums. According to Wikipedia (see footnote 71 of this Wikipedia entry), Escher’s art became well-known among scientists and mathematicians, and in popular culture, after it was featured by Martin Gardner in his April 1966 Mathematical Games column in Scientific American.
