So intricately drawn they are seemingly plucked straight from the imagination of a mad scientist, artist Justin Amrhein's works will give you a pretty good idea of what that might look like. Currently on view in a solo show dubbed "Schema", Amrhein's illustrations precisely map the interiors of complicated imaginary machines, contrasting strong parallel lines and sharply angled corners with organically-shaped valves and snaking cables. With the occasional splash of color, the overall muted color palette balances out the elaborate show of lines.
Whether the subject is as organic as a praying mantis, as threatening as a nuclear weapon, or as exotic as a futuristic device conjured up by the artist's imagination, each drawing brings to light those hidden workings underneath the surface that tend to escape our notice.
"Schema" is on display at San Francisco's Michael Rosenthal Gallery through 30 July 2011.
