Move the mouse.
The twelfth study was an attempt to have cursors driven by mouse movement in both a delayed fashion and by immediate movements. In other words, the position of each cursor is driven by both the cursor’s current position relative to the real cursor and the previous position of the real cursor. The results were ambiguous and had unintentional glitches. Many of the cursors with higher delays rapidly flicker between two positions. Having a single value driven by multiple inputs is a technical issue I’d wrestle with later.
