  • In this short video,

  • we're going to show you how we used animation

  • to make custom playing cards to do magical tricks

  • in TED-Ed's Lesson on synesthesia.

  • Synesthesia is a neurological condition

  • in which two or more senses are paired together

  • to create a completely new experience.

  • For example, many synesthetes see letters

  • and numbers in colors,

  • even when they are printed in black.

  • Or they can taste certain words.

  • For instance, jail tastes like bacon.

  • Because synesthesia generally involves

  • the brain pairing up two or more senses,

  • we paired up playing cards

  • with unique,

  • colorful,

  • and visceral symbols.

  • We then used an animation technique

  • called stop motion

  • to manipulate the cards in ways

  • that would be otherwise physically impossible.

  • And as the cards were flipping,

  • shuffling,

  • and sliding,

  • we used a mixture of animation and reality

  • to ensure that the symbols on the cards

  • did their part to explain the nuances of synesthesia.

  • This type of animation is very difficult to pull off

  • without some planning first.

  • A storyboard is a series of still images

  • that basically serve as a road map

  • for an animation from beginning to end.

  • An animatic is a storyboard in motion.

  • By making the animatic,

  • we were able to review the digital motion for each shot,

  • which allowed us to progressively work out timing,

  • camera positioning,

  • and, most importantly,

  • any challenges we anticipated

  • in the final animation process.

  • How many hands do you need to shuffle a deck of cards?

  • Here, we wanted to emphasize each nucleotide

  • in the DNA sequence

  • and stop motion allows for more control.

  • By shuffling between individual frames,

  • we could ensure that each card

  • had a controlled amount of screen time,

  • in this case, three frames,

  • and that the card's placement was consistent.

  • But sometimes four hands just isn't enough.

  • We use this trick a lot in this lesson,

  • all thanks to one secret ingredient:

  • Play-Doh!

  • By molding the Play-Doh into different sized pyramids,

  • the cards can be held in different positions,

  • always keeping the pyramid big enough

  • to support the card,

  • but small enough to not be seen

  • and to not cast its own revealing shadow.

  • Making an animated movie

  • is like making a delicious layer cake.

  • It's up to the animators

  • to create the many planes, or layers.

  • The use of green screen

  • enables us to shoot individual elements moving,

  • and to later assemble those layers

  • one on top of the other.

  • Using software, we key out the green color,

  • both on the background

  • and Play-Doh.

  • Layer the cards,

  • add the hands,

  • insert a background,

  • and if you planned your ingredients carefully,

  • everything should come together just right.

  • So, grab some fishing wire,

  • glue,

  • masking tape,

  • chopsticks,

  • and whatever else you can find.

  • We'd love to see you make some of your own

  • animated illusions.
