Huge paintings were created on four silos at ul. Chmielna at the Branibroski estate in Zielona Góra. They present an artistic approach to the four elements by Zielona Góra muralists Jakub Bitka and Łukasz Chwałek. 
 
The colorful paintings are on cylindrical tanks 7 m high and circumference d 95 m each. A mural symbolizing a different element was created on each of them: water, fire, air and earth. 
 
The water is symbolized by the icosahedron, but there are many other elements on the mural, including aquatic animals and an attempt to show how life was created and evolved in this environment. The earth is symbolized by a cube with plants and animals. This mural includes primitive man and the cave. 
 
The tetrahedron became the symbol of fire. Here, the artists presented their reflections on the development of civilization, war and the industrial boom. The air sign is an octahedron. In addition to him, the mural includes motives related to the conquest of space and artificial intelligence.
