Octavi Serra uses the structures and symbolism of public spaces to question the systems we live with and find humor in their details. The Barcelona-based artist often engages with signage to subvert its original meaning, like forming a massive arrow pointing left with safety stickers that all individually indicate to exit to the right, or adding opposite directives to a signpost for routes to “hope” and “doom”. Serra also questions strictures of space, like adding “the road is lava” to a painted crosswalk, referencing the universal childhood game, or replacing parallel parking space lines with nonsensical squiggles.
