Many inventions seem obvious once you’ve seen them. Like the wheel, or the hang glider, or the Post-It note. But it takes a special kind of someone to see those things before they exist, and bring them forth to obviousness.
Someone like Jim Gasperini, who has hit upon a really neat trick involving using an animated GIF to toggle back and forth between two slightly displaced photographs, providing a convincing (if somewhat jittery) illusion of three dimensions: Time for space. And given the rarity of such men, who can fault Gasperini for choosing to give pride of place on his page to a nude image of his three-dimensional self. Like Da Vinci with his Vitruvian Man, Gasperini makes his Johnson the proud, still, center around which the universe revolves: Siegfried salutes the sun.
