The city is just one giant playground for French street artist OaKoAk.
Walking around French cities looking for his next canvas, it's normally not too long a wait - all he needs is a small imperfection, a puddle on the floor or a crack in a wall.
The results are blink-and-you-miss-them creations that are simple and playful – for example, a tiny tightrope walker making his way along a crack in a pavement.
“The less I intervene on the wall or the road, the better, especially if I can totally change the sense of the urban environment,” he told HuffPost UK Culture.
Heavily influenced by 90s videogames and TV, his blog provoked a bit of office nostalgia for Mario games and Teenage Mutant Ninja Turtles.
Check out more of his transformations in the slideshow below. Our favourites are the rhino and wind-up mouse, what are yours?
