I like Lex Wilson’s Moleskine art, because the majority of his work is inked to the edges of the pages. He combines diverse patterns from paisley to geometrical symbols, and sometimes includes three-dimensional Escher-inspired objects. Looking at his Flickr gallery, it is clear that Wilson likes optical illusions—playing with spectators’ visual perception. The image at top is an example of that, he is able to make a piece of paper look special by not being just two-dimensional. P.S. the stairs actually spells something!
