Sure you have seen a zoopraxiscope. Is a a device for projecting motion pictures that pre-dated celluloid film strip still used today.

Was invented by Eadweard Muybridge, who was an English-born photographer, known primarily for his early use of multiple cameras to capture motion, and of course, the zoopraxiscope.

This is an experiment that takes his theory and tries to apply in an inverted way, instead of moving images, the reader is in movement.

It may look like this.

## Step 1: Precautions and Materials

First let me tell you that my english may not be the best, but Im not usual to write in an other languaje thats not mine... I'll apprecieate your corrections.

Well, back in the proyect... Its important to have permition to draw in someones street ot wall. If this is imposible, you may consider use a ereaseble material, or print the pictures instead.

When you try to do this, please ask someone to drive you. So you can see the zoopraxiscope without crashing.

MATERIALS:
You will need:
1. A serie of photos.
2. A street or wall where you can freely move a long.
3. Paper, scissors.
4. Paint (washable)
5. Tape or glue.
6. A car or a moving device such a bike or a trolley.
7. A friend who drives you.
8. A toilet paper tube (to use like a viewfinder).

## Step 2: Find a Safe Road

Is very important to find some street that is accurate for this experiment.
And of course to have the permition to do it.

## Step 3: Print

Print a the series of photos.

These are the ones Eadweard Muybridge used, but you can make your own secuence, and even use words.

Now, the size: you can use the a letter size paper.
How many pictures? at least 3 sets.

## Step 4: Paste or Paint

You can make a stencil and paint directly in the wall or the street.
Or you can simply paste them.
Keep the pics in order.

Don't be a vandal.

## Step 5: Get in to the Vehicule

Ask some one to drive you thru the zoopraxiscope!

You have to keep your sight steady. Focus only in one point. You can make a mask to obtain better results.

The mask can be done with a cartboard with a square hole in the center and paste it in the window.
Or... you can use a toitet paper tube as a viewfinder. To see only in one spot.

You need to move in a constant velocity. You dont need to go very fast.
Also depends in wich vehicle you are.

Hi! Do you have a video that shows that street zoopraxiscope in motion?

There are similar installations in the Boston 'T' underground system. They take advantage of controlled lighting to instantaneously illuminate the posters as the train zooms past. Could be a very simple circuit in use (triggered by proximity or beam-breaking or something).

Don't worry, the message gets across just fine! I would hate to try to post in Spanish, No one would understand...

Thanks for an unusual posting. I had to look up Cuernavaca to see where it is, it sounds like a great place.
