Mehdi Ghadyanloo is known for his urban murals. Paintings that are dreamy and imaginative and elements such as children, slides, and kites play a central role.

Ghadyanloo was born in Karaj. Since childhood, he got acquainted with art due to his mother's interest. After finishing high school, he entered the Faculty of Fine Arts at Tehran University and studied painting. For graduate studies, he went to Tarbiat Modarres University and received a master's degree in animation. In 2005, following a city festival organized by the Tehran City Beautification Organization, he turned to mural painting, and this was the beginning of Ghadyanloo's professional path as a world-renowned muralist. In 2006, he performed one of his most famous murals in the market of Tehran. In 2015, he painted one of his most significant mural projects titled "We didn't start the game" in the Shoreditch neighborhood of London, which is considered one of the leading centers of mural painting in the world; An image of three children playing tightrope under an arch and two giant crows watching them through a hole in the roof.

In a report about this project, the Guardian referred to Ghadyanloo as the Banksy of Tehran. Places such as Dewayne Square and the Greenway area of Boston, USA, have also hosted other murals by Tehran's Banksy. Using optical illusions, Ghadyanloo creates negative spaces like a room on the body of buildings and arranges his elements in the heart of this space. Interfering with the objective logic of things causes his works to find a dreamlike (and sometimes nightmarish) state; Suspending elements and forms in the space, creating an opening on the ceiling of the rooms, the coexistence of different historical moments, playing with the dimensions and proportions of the elements provide the possibility of surprise and imagination of the viewers. In most of these works, the environmental qualities, such as the sky, local architecture, etc., extend into the heart of the painting. This relationship between the work and the environment plays an essential role in forming these works' narratives.

In addition to mural paintings, Ghadyanloo has also followed painting on canvas. Although these paintings are similar to his murals regarding the spatial organization and execution methods, they focus on more personal concerns. The dominant space of his paintings are closed rooms with a hole in the roof. In the middle of this room (or several adjacent rooms), elements such as children's slides are depicted, or abstract volumes and surfaces are placed. The glossy and transparent effect resulting from his representational techniques, bright colors, and monochrome spectrums create a kind of fantasy atmosphere.
