Help, guides and the small print.

Write to a pretend team.

About this concept
What is real, and what is simulated.
Real
The interface, the geometry and unit maths, the planner, the forms, the dark mode and the accessibility work. All run in your browser.
Simulated
The device. The pendulum is a simple damped model, and phone tilt only reads your own phone sensor to move the drawing.
Invented
The product, its specs and prices. There are no customers, reviews, press or company behind it.
