Zeller's father was a scientist, so from a young age he would regularly visit his father at work and was amazed by the scale of machinery, this has inspired a lot of his works today.
Zeller originally started in sculpture, and has translated into his drawing work as he is still very interested in textures and making something 2D appear 3D.
Speculative Symbiosis, 2009, Ink and Acrylic on Paper.
He mostly uses ink pens called rapidograph pens, and he can fill these with any colour ink or mix any colour, he likes these pens because they can create a consistent fine line. He also uses a smooth surface paper so the ink doesn't bleed and to achieve a crisp, fluid, clean line.
Interalized Connectivity, 2007, Ink and Acrylic on Paper.
Please find a video of Daniel Zeller talking about his work and techniques.
