Minneapolis illustrator Bill Rebholz creates illustrations and patterns for fun and explorative concepts. One of his projects which explores fabricated realities is called "Pseudo Pspace" and imagines what the set of a faux moon landing would look like. Another project by the name of "Pick and Choose" investigates the "Polar Vortex." Bill says this piece was intended to channel warmth. In addition to these projects, Bill has also worked on multiple campaigns, murals and has also created a few typographic alphabets. His website is worth a look.
