3D street art by Melanie Stimmell

If you’re charmed by kids and their sidewalk chalk messages, check this: the 500-year-old tradition of giant sidewalk murals that deceive the eye (before they’re existentially washed away by rain). Former South Park Lead Technical Director Melanie Stimmell became so enamoured of the art she quit her lucrative Hollywood post and took to the streets globally. Her work includes a staggering rendition of the Sistine Chapel ceiling, a UFO with a baby inside, a femme fatale in the open mouth of a rhino… The only woman to earn the title “maestra madonnara,” or “Master Street Painter,” in Italy and Germany, Stimmell is known for interactive art you can get right inside.
