anamorphic moirée, masked glas

Perception changes with the point of view. 
A linear filter hides or reveals certain lines of a sujet, depending on the spectators position and perspective. By combining the effects of anamorphosis and moiree your vision is truly individual and interactive.

clay on floor

First tests of a robot that prints on the floor. As it travels along a spiral path, it shoots dots of water and clay onto the ground, creating a gridded large-format image. The subjects are endangered small creatures, in this example a caddisfly. Over time, the dots of clay dissolve and decompose, and the image fades and decomposes, as do the drastically declining populations of the insects depicted.

global warming, coppersphere, acetone, ink, silikontube

If we put our hands too tight around the globe, terrible things can happen. Fortunately, when we let go, nature finds it’s way back.

The copperball is filled with inked acetone, wich expands very much when temperature rises. The warmth of hands is enough to build up pressure, that pushes the black liquid through the transparent tube. After removing hands the acetone slowly cools down, contracts and withdraws back into the „earth“.

Repeatedly I wondered about the dead bugs at home. So I decided to collect them to make something one day. Unexpectedly, I came across an article in a Newspaper that clarified the little creatures background.

„The Chinese Garden in Zurich was a dubious gift from the Chinese city of Kunming in 1994 as a thank-you for the foreign aid offered by Switzerland to China. The yellow roof tiles of the pagodas did not survive the cold Swiss winter and needed an early replacement. New tiles were sent from China to Switzerland to exchange the damaged ones. As a blind passenger in the wooden boxes of the Chinese Emperors Brick Factory, Halyomorpha halys, the brown marmorated tree bug traveled along. Since then, the bug spread rapidly within Switzerland. Also referred to as “stink bug”, the bug is classified by farmers as pest and especially damaging to fruit crops. As soon as the temperatures fall, the bugs seek shelter indoors in warmer temperatures.“ Tageswoche 5.4.2018
light and shadow dialogue, print on glas

Light and shadow have a litte chit chat.
Light casts a message into shadow and the shadow into light. The print on the glass grating is aligned to a spotlight. By turning or changing the eye point, one message appears and the other disappears in an anamorphotic way.

lampshade, casted ceramics

Light is magic.
In this case it reveals hidden pattern. The perforation follows a binary order of either holes or cavities. The identity of the lamp can be changed by switching the light on or off. Turned off it is even and quiet. With light from within the regular pattern turns into lacy softness and reveals its ornamental DNA.
The lamp is made of casted ceramics with a 3D printed mold.

i love graffiti, spraypaint

The art of graffiti is very volatile.
Especially on legal graffiti walls some artworks are sprayed over every day. This builds up a massive spraypaint body, solid enough to cut out a simple message as a tribute to all graffiti artists.
With the help of a milling cutter each letter was taken from a different spraywall, what felt like cutting through color and time. Placing the letters vice versa reveals the very first layer of colors on the backside, in some cases years ago.
