Strange Things sometimes happen...

Was trying something that I even don't know what...
At G2F I was using the 4Players and the 4Missiles joined as 5th Player PF3 colour using PRIOR0.
As they are one next to the other and I was using ANTIC4 charmode as they begin in the 'BadLines' I get more changes than allowed.
When I run it on Emulators I get this:

(between the large cells there's a scanline that is the 'error' because of the 'BadLines).
And more: as the 4Missiles that are the last ones at the bottom and don't thinking in that, I had them in a darker luminance.
When I saw the screen what I saw?
That a linear 2D seems indeed a 3D tower with the corner.
It just 'fool' our Human eyes.

This is a possible use for something.
It can be just PFs or like here the dark part it's Player colour where the light one it's the Player Oring.
For example, using PRIOR0 and these towers beeing PM2 and/or PM3 we can have dark part PMGs colour and lighter part Oring PF2 and/or PF3 (we can even get there Windows and Doors if we overlay there PF0 and PF1).

Then I tried with more than one Tower:

And even more:



(Try seeing this 'zoomed and at some distance)
Isn't this 'fooling' our vision?
