  • presenting a user interface comprising;

    a control area comprising an ellipse;

    a user-manipulable control element located within the control area, wherein the user-manipulable control element comprises an arrow having a curved body and a variable length and a variable direction, and wherein the length of the arrow specifies the speed, and wherein the direction of the arrow specifies the direction, and wherein the curved body of the arrow comprises an arc of the circumference of the ellipse, and wherein the tail and the head of the arrow are located on the circumference of the ellipse, the arrow pointing along the circumference of the ellipse; and

    a multiplier that indicates a number of revolutions when the length of the arrow is larger than the circumference of the ellipse;

    receiving user input via the user-manipulable control element, the input comprising dragging a head of the arrow in order to set the arrow'"'"'s length and the arrow'"'"'s direction; and

    animating the object based on the received input.
