A hand holds a small cardboard prototype in front of a wall covered in drawings and notes

A close-up photograph of a dry erase board with taped up sheets of brown and white paper in various sizes with some overlapping. Each piece of paper is covered with hand drawn black ink sketches, designs, and mockups along with text. Lines of green text on the dry erase board are mostly hidden underneath the paper. A light-skinned left hand appears at the bottom center, holding a small black rectangular device.
