Look who's just resurrected. 
Long time no see. Glad to see you back on and ok Radim. :beer:

Yes it is. I just checked the URL's listed in your post at they are blocked for me. I'll have to check them out when I get home.Ah... It's my temporal webhosting now. Maybe this is the reason. Ok, than you'll see it home.![]()
Glad to see you back, Radim. I have been wondering what happened to you. I can't look at your image either, but may know what you are talking about. It isn't a hologram, but might be an image that can be seen in a picture when you focus your eyes past it. I forget the correct terminology for this but it has been done for years by others. I have known about it for over 30 years now. I am currently out of rep, but will get you when I have more.
Hey Radim nice see you have returned to LPF ---nice post---no trouble seeing the pictures here with Foxfire on laptop. +rep
Looking forward to seeing some new laser painting.
Whatever became of the Optotronics RPL II 532nm 1400mW? Have you found it to be useful tool for laser painting yer?
Update on the "Hologram" question: Where is the aditional information stored?The hypothesis is:

Here you can see why I'm so insanely curious about this strange green square. In holograms, the information about 3D space is stored in the speckles (rather than "wavy" pattern as shown on pic below).

That display (OLED is the best I found so far, that's why I use my mobile to explore interference patterns of my artworks) is able to cause interference in "unwanted" color change when viewing under various angles. Here this little imperfection of display technology is used to get the information hidden/coded in the speckle/noise of the photograph.
Camera sensor:
Type: CMOS APS-C
Size: 22,3 × 14,9 mm
Resolution: 6000 × 4000 px
As you can see in original image detail - there are just a few pixels from full 24,2 Mpx available. Here at these dimensions some holographic effects based on phase difference of 532 nm could happen IMO.
What do you think?
Still have a large square blocking the center of your photo and, now, avatar. It says "QuickPic" at the top left. If I could see what you are talking about, I might know what is causing it. BTW, + Rep. FINALLY!
It is just background wallpaper in my mobile (earlier artwork), do not pay attention to it. It was much easier to see the depth with some frame, so I left it as I observed it first time (in task manager). The image is the green square itself. It is better to see it from distance and side a little bit - in dim room (light reflected makes it harder).
Thanks, I have spreading limit applied on you. Strange after such a time. Seems I need to spread some.
Edit: Also it is better to look away, focus somewhere else in the room and than go back to the screen and it should appear as the green square is below. If you focus in between the square and frame, the 3D scene is there. Still it is very shallow and 3D is somehow "flat".
Hey, Welcome back my Friend!! :wave:
I'm glad to see you back in here!! :beer:
