If you select a frame that's moving to the right, that would make the blue disc move to the left but it doesn't because we then track it to keep it on the screen - this is done so that we can see the events play out there for longer than a short time. If everyone had a wall-sized display with 20,000 pixels from one side to the other I would have programmed it differently and not bothered to track it.
the coin cannot both be circular in that reality and elliptical at the same time.
A grid representing ether may then help us to understand faster that a box is at rest when we chose it.
It would also be better if we could change the frame without changing the speed of the target, and it would help if it was a key that we would hit to change it. By the way, I just noticed that it was not the speed of the frame that we could change, but the speed of what you call the target, which is the blue part of the simulation. I discovered that while changing the frame with object a.
But even if I now know that, it is still a bit confusing for me not to have ether in the background.
Object c has four boxes getting away from the target, but the orange and white ones are both following the same diagonal direction while not being deformed the same, so I suspect it is due to a bug.
I also suspect that the four diagonal blue boxes on object d contain a bug, because the are not square when the other four are.
The fabric of space remains fixed to the screen, but it does become distorted, as shown by the blue square in example object set "a". Whatever that blue square does, you only have to imagine it as a square in a grid to visualize what the rest of that grid would be doing.

You are reading things into the post that aren't there.
Perception does not alter the object being observed.!
I now understand why you call it a target, so I think you should describe it like that on your page, and maybe you could put a real target in the beginning when people select object D at the beginning and hide it after when they change the velocity of the target.
I already saw that kind of deformation on wiki's Relativistic Doppler effect page but I didn't understand it. Does it mean that the objects at the front would look dilated and those at the rear would look contracted? If so, I'm possibly missing something because if I am moving towards an object, it seems to me that the light from the rear part of the object would hit me sooner than if I would have been at rest, so that the object should look contracted, not dilated.
Now if we use a reference frame in which the red box is considered at rest, then to me, the camera has to change reference frame too otherwise it doesn't make sense.
But why would a god's view change when we change reference frame?
There's only one fundamental "God view", and that's tied to the absolute frame. The "God views" for other frames are ones that would be the fundamental "God view" if they were the absolute frame.
The absolute frame is c.
]In my example with the blue circle and the red box, the box would be moving away from the circle and it would look contracted in the direction of motion if we would take a picture of it while the camera is at rest in the circle's frame. Now, tell me what would happen to the picture if I would select the box as the reference frame? Normally, it is the circle that should look contracted, and it should be getting away from the box too. But when I try that on your objects, nothing changes, the box is still getting away from the circle, and it still looks contracted.

The Light as a Super Reference Frame https://gsjournal.net/Science-Journals/Research%20Papers-Relativity%20Theory/Download/5858It's a mangling of language to call light or c a frame. Light moves in an infinite number of different directions and light moving in each of those directions would be at rest in an infinite number of different "frames" (none of which behave like reference frames). The actual reference frame that comes from light is the absolute frame through which light travels at c, and labelling that frame as LCS is just making up another name for "the absolute frame".
c is energy. Energy is of space.
I must correct your ill informed logic. c is a constant speed 300,000 km/s
If you select the set of objects called "d", you'll see eight boxes (round the uncontracted blue disc) which are all contracted to half their rest length.
If you select a frame moving up/down/left/right at 0.866c you should find that one of the red boxes doubles in length because it's now at rest in the selected frame (while the blue disc will be contracted instead). None of the other boxes will be at rest, so they will continue to show contraction, although two of the yellow ones will be less contracted than before because they are moving in similar directions to the uncontracted red box. If you are able to use the number keys to change frame (I still don't know if that works on your machine), pressing 2 should make the red box at the bottom fully decontract, while 3 will do the same for the red box on the right.
They move at a tangent to the blue objects, so they should be contracted in the direction of their motion, but they are stretched instead.
I reread your explanations on MSB, and I have the feeling that you are accounting for two different relativistic phenomenon at a time: the contraction issued from the MMx experiment, and the way we would see an object approaching or getting away from us at a relativistic speed. A directly approaching object would look stretched because we would see its front before its rear, and because the front of the object would thus have traveled toward us more than the rear, and inversely, a directly departing object would look contracted because we would see its rear before its front, and because the rear of the object would thus have traveled away from us more than the front.
An object moving at a tangent should thus look stretched before it hits the tangential point, and contracted after, thus it should look normal right in the middle. Now, I think you're adding the contraction from the MMx in the equation that calculates the coordinates. Is that so?
Only pressing 2 or writing 2 changes the look, but it doesn't change the same way: pressing 2 deforms more the object than writing 2.
You also said that the blue dots were representing circles, but on your page, we can select 16 objects to get their coordinates, and 8 square-like objects are made out of blue dots.

When you press the 2 key, the bottom red rectangle displays its rest length, this being twice as long as you see the rectangles in the absolute frame view (key 0).
The ref-frame camera program does not show any kind of stretching or contracting of the latter kind - it only shows the length-contraction of relativity.
All objects are programmed in with absolute-frame coordinates, so the rectangles are programmed in at half their rest length because they're all moving at 0.866c. When you view from the absolute frame you see them maintain the same amount of contraction wherever they go. When you switch to a different frame (e.g. by typing the 2 key), you will change the lengths of all the objects, but again they will then maintain those lengths so long as you view them using that frame - their lengths don't vary as they move around. A ref-frame camera takes "God view" photos which can be viewed like "God view" video and they are totally free of the kind of delays that cause the kind of distortions you're talking about.
The program was not designed to handle curved objects (it can only deal with shapes with four corners), so the blue disc has been constructed out of 8 objects, four squares and four non-squares. It is to be regarded as a disc.
