Welcome to my work !

My thoughts are living in an environment of visibility in a real and imaginary sense. So consequentially everything meets in a single medium: the drawing. I hope you will enjoy them also as my games, works on art history etc.

This book presents my graphic work. For me, drawing is not just a tool for the aesthetic confrontation with the world. Rather, it is the platform for any mental work.

Triangular – play now !

“Triangular” – also known under its old name “Triadis” – is maybe the best game I´ve invented. Because it is not available at the moment I´ve programmed a browser version. So you can play the game online against each other (this strategy game is for two persons) or against the computer respectively the server. Also works on tablets and phones. The Rules are also online.

Play know in your browser !

Xtremori! Memo game

My game Xtremori! is the worlds only double-sided tile-matching game. The object is to find two tiles with the same combination of images: a pair! The tiles show only a view different images, but every combination of them is twice in the game. The game was often published nand received as Xtremori!® the well known “spiel gut“-award. I hope it will be available again soon.

Folding puzzles – NEW !

Already in 1995 the “Spektrum der Wissenschaft” published a special edition with my folding puzzles (sold out). The puzzles are just a simple piece of paper with a folding grid congruent on both sides containing the “tiles” of the puzzle. The rules are simple: Just fold the paper using only the lines of the grid until you reached the target image. Try it now:
