Things I Like
Whenever I go outside you'll probably find my carrying a bagpack with my DSLR and a few lenses. I love capturing the world around me and creating promotional photos of my products. You can find a selection on 500px.
Roomlight adapting to your music? Couch with motion sensors? Table with NFC tags? Laser-cut autonomous robots? 3D printed catapults? Powerplugs that detect when you are home? Welcome to my world!
Honors & Awards
