redraw exchange time with width exchange time with height

This page records the motion of a mouse pointer and redraws it, swapping the time dimension with width or height. It illustrates what the path of the pointer would look like if it were moving across time as if it were width or depth and passing through width or depth as if it were passing through time. To use it, draw a line by dragging the mouse point through the rectangle. Then click one of the buttons to redraw the path.
