If the leaping grenadier robot doesn't look familiar, that's because it's one of the many foes found in the Strider 1989 video game for the first Nintendo Entertainment System. for people who have played it, this picture was deliberately designed to evoke the reaction of moving your left thumb down and to the right while your right thumb is pressing jump. i.e. Whenever the player sees this split-second image on the screen, the move that would get Strider Hiryu safely into a perfect position for a counterattack is to do a slide kick underneath the robot before it lands on top of you. I really like how this picture's composition came out, too.
