Principle of motion camouflage. An attacker flies towards a target, choosing its path so that it remains on a line between target and a landscape point near start of attacker's path. Attacker thus looms larger as it closes on target, but does not otherwise appear to move. Newly drawn, based on analysis of papers such as Lewis Dartnell "Motion illusions &amp; active camouflaging".
