that probably dosent make sense anywhere except inside my head...

ah, but think it as a laser pointer (or flash light) and walk up close to the wall, move it, and you'll get a smooth very precise movent. Now stand further away, and the same slight movement, moves the dot a much much bigger distance and faster on the wall.
