Ink on paper, Atoms to Pixels
Human at the Helm, Pen in Hand. Every product starts as a line. Thinking out loud — in ballpoint, in marker, on the iPad Pro — the human craft of drawing will gain in importance.
Sketching is where the work begins — fast, efficient and honest. It's how an idea survives contact with reality before anyone commits anything to atoms. Ink on paper, atoms to pixels.
Two tools, one habit: a pen that's always in a pocket, and the iPad Pro for when an idea needs colour, layers and infinite canvas.
A long collaboration with Concepts — the "smarter sketching" app — led to becoming an official Concepts Creator, sharing technique with their community.
