Behind the Scenes: How a Bot Draws Your Card

A peek under the hood at how vector paths, AI prompts, and a really clean pen become a keepsake.

Step one: pose and scan

Guests step in front of a camera on a stand and get a short countdown. The attendant handles framing, so nobody has to think about anything except how they want to look.

Step two: turning a photo into lines

The image is processed into a stylized portrait, then converted into vector paths — a set of continuous lines a machine can physically follow. This is the part that makes or breaks the drawing: too many paths and the pen scribbles, too few and the face disappears.

Step three: the arm draws

A robotic arm holding a fine-tip pen traces those paths onto your keepsake card, one stroke at a time, in front of the guest. It's mechanical and oddly graceful, and it's why people film it.

Step four: hand-off

The attendant lifts the finished card, and the guest walks away with it still warm from the pen. If you've added the live-view TV, the drawing has already appeared in the gallery on screen before they reach the table.
