For the past four years artist Michael Pederson has been leaving miniature street "interruptions" across Sydney, Australia as part of his project, Miguel Marquez Outside.
The installations are small and often hidden in places someone in a hurry would easily miss.
"I like the idea that a lot of the work is hidden in plain sight and has to be discovered by a passerby," Pederson told BuzzFeed.
Pederson said his pieces can sometimes even act as a "strange public service announcement."
The pieces are comical in nature, but they can also serve as a more serious reminder to be aware of your surroundings.
Though Pederson stumbled into this particular art style almost unintentionally, he's taken inspiration from artists such as Jenny Holzer and Slinkachu.
"Because my works are generally small and somewhat removable, I haven't had any trouble (with law enforcement) so far," Pederson said. "I remember a security guard giving me a 'thumbs up' when he saw me installing a piece a couple of years ago, which was nice."
While sometimes Pederson will hunt for the perfect location to put a completed work, other times it's a place or object that inspires his art.
"I like underscoring forgotten or neglected aspects of the urban environment and exploring the idea of the private self in public space," Pederson said.
Though some of his instillations may seem a tad sardonic, Pederson hopes the art will give by-passers a moment to think.
"Ultimately, if a piece stops someone in their tracks and causes them to think or smile for a moment, I'm happy enough with that."
