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.
