Okay, well I found some data or at least I think it's data... and wrote a python program to read this data. It wasn't too hard to read but I think there may be another step I'm missing as I still get goobly gook... sorry to be cryptic but I don't want to give too much, but please pm me if you want to talk more on this!

Maybe this can be answered: would I be correct to state the data as calling it 'true and false', 'yes and no', 'up and down', 'left and right' and etc?

Nope :geek:

Thanks, keeps me from guessing any more on that path, now I just have to figure out what I did find! So a follow-up question, my python program to analyze each pixel, is that still relevant?

Yeah that would be useful :)

Is this some form of data matrix... could it be read like a barcode?
Also, you said that the rotation was the product of your laziness. Does this affect the answer at all? Would using one of the rotated ones cause the answer to be wrong?

I wonder why the image is 8 by 8 big blocks. 8 bits represents one char, 8 chars could be a password. I have 'picked' the pixels and a pattern is left. Not directly binary I have seen, and a message of 12288 chars ((192*192)/3) would be to big. So maybe evaluating the matrix per big block/pixel?

And about the rotation and your lazyness... Is that because a bitmap is read from bottom left to top right?

Am i on the right track here?

thanks

It's not a datamatrix. Tried that. It doesn't have the appropriate border around it, so I even tried adding one. Still nope. Nines, I found it very interesting that in the top row of each superpixel, there's exactly one pixel that is *different*, and that its location in the top rows varies between the superpixels. However, I am having a huge amount of trouble getting any readable data from that, and it most definitely has nothing to do with any rotation in any blocks. In fact, I have absolutely no idea what rotation you're talking about.

Also, is "Pick a pixel" a hint?

Data matrix is an interresting word, you might want to look into that again. After all, its insert number here of them, which might be insert prime number here times a insert something else here.
And with the stray pixels that are off, what else is there to wait for?

If we knew how long it was it would be so much easier.
