Supplies You'll Need:
- Compass (the circle making kind)
- Ruler (or the straight edge of the nearest thing lying around)
- Print outs of video game sprites (or you could draw them by hand)
I found mine here: Mariomayhem.com
- X-Acto, Box-cutter, or scissors
Step 1: Cutting Circles & Dividing the Frames
You'll be cutting out 2 circles. 1 shutter spinner (cardboard, larger), and 1 animation disc (paper or cardboard, smaller)
The animation disc should be about 2-3 inches smaller.
I used cardboard for both to make the scope hardier, but paper would work fine for the animation disc.
Be sure to clearly mark the center dot (where the compass needle was). Everything will spin around this.
Making the Frames:
Decide how many frames you want your animation to be.
More frames = smaller "pizza pieces" = smoother animation = less details fit in a frame
Less frames = bigger pizza pieces = chunkier animation = more details fit in a frame
I did 33 for mine.
There are great tutorials for how to use a ruler and compass to divide up a circle, and they will be more exact than my method which was:
-> Photoshop's "Polygon Tool" and make a starburst shape with the desired number of points
-> print out
-> tape to the center of your disc
-> mark a dot at the points of the star
-> Use a ruler to connect the dots out
Making the Shutters:
Center the animation disc on the shutter spinner and trace it. This line will show you how long your shutters will be.
Make 2 vertical cuts on the shutter spinner along each frame line, then pop it out.
Note: Shutters that are a little long don't hurt anything, since your animation will cover them up.
Step 2: Animation Disc
I plan it out with dots and lines before I glue or draw anything.
Dots are much easier to erase and it's no fun to be halfway through and realize your animation is off.
A Loop, not a Story
Remember, this is a loop animation with continuous motion. Your last frame should lead you into your first frame.
It's different than a flipbook with a beginning and an end.
Keyframes & In-Betweens
Chop your animation is half, then quarters. These keyframes will keep you from working ahead too fast (or falling behind).
Step 3: Spin It!
Tape the animation down so it stays put.
Spin it in a mirror. It only works if you look through the shutter slits.
If you made a smaller, lightweight phenakistoscope, then a thumbtack in a pencil eraser is better than jamming a pencil through the center hole.
Note: After 5+ hours of fixing, checking, and minor corrections you may feel a tad sea sick!
