English artist Tristan Surtees and French architect Charles Blanc are art practice Sans façon, which literally translates to "without unnecessary social ceremony." They specialize in perception-altering pieces that interrogate people’s relationship with place. Case in point is Limelight: Saturday Night, in which two streetlights are replaced with theater spotlights, inviting passersby to engage with the street in a new way. The piece has traveled to 16 cities worldwide since 2010; the above image is from Miami in 2011.
