Marker Portraits by Mr Frivolous
Thru Abduzeedo and other inspiration websites, you probably have seen almost everything in terms of art, from wicked installations to regular acrylic art, there are no limits to creativity.

Yep, regular markers, like the ones we used to draw when we were kids and nowadays we mostly use for sketches, just check this guy out.
