M.C. Escher versus Rob Gonsalves:

The DIGG website links to a page with artworks by Rob Gonsalves, suggesting he is "M.C. Escher reincarnated." I think Gonsalves is better than that. Escher created a syle of trompe l'oeil art based on mathematical shapes, forms and patterns, but he was too much of a draftsman, and his pictures tend to be emotionally cold. Gonsalves follows Escher's style, but his pictures have much more humanity, warmth and mystery. For example, see this one, or this one.
