This is the second episode of the Magic Eyes in Motion sequel. If you have not tried the first episode, search for "Magic Eyes in Motion" on the Market.

If you don’t know how to "see" stereo scene by crossing your naked eyes (hence the name cross-eye or magic-eye), you may want to Google the internet on that topic first.

How to Play

In this episode, you will fly in the outer space. The setting includes one space station and 7 space ships. Each ship has different color (red, green, blue, cyan, magenta, yellow & white) and shading so that they can be distinguished from the unreachable stars (as background).

Your mission is to bring the ships (I call then LIS in this game) back to the space station.

Use the following four actions to control the game.

1. Tap the screen. This action is used when:
- At the start-up, the game enters standby mode and waits for your tap to begin. Before you tap, adjust the roll & pitch (see below) of the screen to best your view angle.
- You can "grab" or attach an LIS when you get close enough to that LIS. Its color & shade will become transparent to signal that you are within the attachable distance.
- Another tap when an LIS is attached will release that LIS.
- If you tap and neither an LIS is within attachable distance nor an LIS is attached, then:
* the background stars will blink (dim) once so that you can see better other LIS out there among the stars, if there is any; or
* the stars do not blink because no LIS is in your facing direction (the half-sphere you are facing). Try to turn left-right or up-down and continue tapping to find one.

2. Touch and hold the screen. This action will move you forward. You can bump into the station or an LIS if you fast forward all the way.

3. Turn the screen to left or right (adjust roll angle). You rotate the handler to turn left or right when you drive a car; just like that. You rotate the screen counter-clockwise to turn left and clockwise to turn right. There is one catch though. Because the left and right images are fixed on the screen for your both eyes, your head (and hence eyes) will need to tilt accordingly when you turn the screen so that both eyes can receive the correct images to give you clear depth perception. My experience is that it’s not that difficult but does need a few round of exercise.

4. Flip the screen to up or down (adjust pitch angle). Flip the screen face toward upside to turn your fly direction down, or flip the screen face toward downside to turn your fly direction up. This action is very similar to when you hold a piece of glass (as a view window) and try to see things around you through that glass panel. Your depth perception will not (virtually) be affected by this action.

So, how do you bring the 7 LIS back to the station? Firstly you need to identify where they are among the stars by searching for spots with bright colors. Then move forward to one of them and attach when getting close enough to the target LIS. Fly back and into the station through either gate (hole) and release the LIS. Repeat for all LIS.

Make sure you release the LIS within the station to score. Both gates will close when you fly into the station.

A timer will display the time elapsed since you tap the screen to start the game. The timer stops on the last LIS been release inside the station. See how fast you can complete the mission. My record is 7 minutes & 19 seconds.

This game will not record high scores. And you will have to manually restart the game if you want. Just press the "back" or "home" buttons on your phone and go to the app page and start the application again.

You saw "Magic Eye" in still pictures, and now, Magic Eyes in Motion.

A brief note on depth perception

To device stereo audio to fool our ears into "hearing" stereo sound, is way much easier than to device stereo image to fool our eyes into "seeing" stereo scene. Firstly, the scene (be it still or motion pictures) has to be produced in such a way that the "depth" information is encoded into the scene seemlessly. And secondly the viewer will need a device to mount over their eyes in order to decode the "depth" out of the sene. For example, to see the stereo 3D effect (the "depth" of a scene) in a moive theater, you need to wear a pair of specialized glasses.

One of the most "handy" way to see stereo 3D effect has been known for decades as the "Magic Eye." It's handy because, while the production of the stereogram encoding the depth information is just as tedious as in other 3D motion pictures, you don't need to mount anything over your eyes; the naked eyes will do the trick.

But then, if you have not yet had the wonderful experience of Magic Eye, you might want to google "Magic Eye" for some hints and tips as to how you can get started fast and easy. Or, if you have been a happy Magic Eye person for years just like me, then read on...

Magic Eyes in Motion

Now you can watch and play the stereo 3D animation by using the very same Magic Eye. Just position the phone screen in its landscape orientation and place it in front of your eyes 20 to 40 cm away, just like you have been doing the Magic Eye before. Lo  and behold, a hexagonal tunnel spins in space and a few astroids flies through the tunnel and come toward you.

How to Play

At the start-up, this application enters the stand-by mode and await your tapping action on the screen to start. Note that the text at the bottom of the screen is NOT prepared for the Magic Eye.

Starting from Level 1, and through Level 7, you will have 60 seconds at each level to retrieve the flying astroids coming through the spinning tunnel. The spinning tunnel exerts a centrifugal force on the astroids and thus pushing them toward the walls of the tunnel. The objects will crash and burn when hitting the walls of the tunnel, or arrive at your side safely if you manage to drag and thus slow down the spinning speed of the tunnel. Slower spinning speed exerts small centrifugal force, you know the physics.

For each object arrives at your side (or rather, for each object you catch), you get one point. You need at least one point at each level to advance to the next level. The flying speed (toward you) of the objects decreases, and the idle spinning speed of the tunnel increases, as the level goes from 1 through 7. You know what I am doing.

If you get through Level 7, and I must admit you gotta be so good at touch-screen drag control, the game will loop back to Level 1. And at each loop back, the flying speed (toward you) of the objects, level to level, will decrease further and further.

For the beginners, Level 1 is designed to get you familiar with the scene. Astroids at this level fly fast enough to reach your side (and score) regardless the exerted centrifugal force. You don’t need to drag the spinning tunnel at this level, but of course you may choose to as a exercise. Starting from Level 2 though, you will have to drag on the screen to slow down the spinning.

So, have fun watching and playing. Be aware of the astroid crash-bang audio effect. It could be very loud and noisy to other people near you.

What's next?

We will fly through the tunnel and out to the Space for some adventure. Coming soon, I hope.
