I'm fan of Fabian Haeusermann' works, I love the resized-repetition process he uses to create his pieces. Fabian was the author for the fourth Special Post here at Triangulation where you can see his previous work.
Most of Fabian Haeusermann' works are quite small (A4 and smaller), he often uses a technical ink pen that allows him to work precise. "It’s a brilliant tool for the cross-hatch technique: It allows you to shade the drawing until it’s almost black - but you still can see the textures." See more;
"My works are usually based on clear geometric shapes like circles, triangles, rectangles... No matter how many details the image contains: It should be based on a clear composition. I like the combination of details / fine textures and clear geometric shapes. I prefer to have a vision of the geometric composition before I start to draw. Most images are concentric, they have a clear center. I also like symmetry. I try to use as little colors as possible. Colors should have a clear function, a symbolic meaning instead of just beeing sweet and decorative.
I also like to use the computer to downsize what I’ve drawn on paper, then print the reduced size version on a new A4 paper and go on drawing ...As soon as I’ve filled the new A4 paper I downsize and print it again etc. etc." - Fabian Haeusermann
