By shaking the phone/tablet you clean the screen, by rotating the knobs you express your drawing ideas.
By rotating a knob, you draw perfect lines. Use two fingers to twist both knobs at the same time to sketch something original. Try your skills and draw a circle! Your drawings are automatically backed-up.
