Gerhard is fascinated by the expressional differences of sculptures and also holds a diploma in sculpting. He purely creates artworks out of his intuition and he is influenced by the medium like hardness, texture, regularity, existing lines or structures. This needs to be considered in order to achieve a harmonious result as well. He likes to play with
light and shadow games in order to achieve certain effects or illusions and he also believes that all space is already used. That means he can only release those objects to freedom. He also implemented the 'harmony lines' which follow universal laws and express even in an chaotic environment an harmonious outcome at the end.
