Artists' Location Morphs
© 2011, Martin Rinehart
Location morphs: Motion! You put an HTML element in motion by morphing its left and top styles. If the left and or top change just a bit from frame to frame (our HTML "frame"s are 50 milliseconds) you create the illusion of smooth motion.
The human eye has been wired to see motion since this was a basic survival skill. Your prey gives itself away by moving. So does your predator! You can use this instinctive reaction online to guide your viewer's attention.
Disney artists learned this fact, carrying the knowledge from cartoons into feature films. When you watch one, watch yourself focusing on the one moving element in an otherwise static scene.
Thanks Disney for Dumbo, 1941.
