He works as assistant of painter Petr Říha at VŠUP Prague, besides the art of sculptures cooperates with various architects and designers.
Regarding the form and size, the primary inspiration for the installation emerged from Megalodon, a prehistoric shark. The author himself perceives the object as a shape archetype that can be found throughout the animal and plant world. Location in the pool induces stress and uncertainty (what is happening beneath the surface?), adding dynamics to the statue. Superficially clear shape takes on many forms, including the night one, and provokes the imagination of viewers passing by.
