Mariusz Kruk's work undoubtedly lies at the heart of the development of Polish art in the 1980s. What distinguishes him from his contemporaries is his original and unconventional choice of materials used to create his individual works. Kruk reaches for objects neglected in artistic discourse, such as cardboard, tyres, string, etc.
In his works, it becomes most important to strive to catch moments somewhere between micro and macro reality. The use of materials that are usually underestimated and considered insignificant, of little sophistication, further enhances and emphasises the inattentiveness of perceiving those moments in between that constitute the happening - the existence of causes of events and the effects that bind them.
In addition to the aforementioned fantasy-lyrical installations, he also realises himself in the mediums of drawing, painting and poetry.
