I opened the file in notepad, noticed it was originally a photoshop file. It also mentioned layers. It 's probably nothing, given how pretty much anything painted in photoshop would have layers, but I tried to see if I could pull it into Sketchbook Pro as a tiff or psd file to keep the layers. No luck. IDK if you or anyone has true Photoshop, but it may be worth a shot if you already own it. Sketchbook Pro wasn't able to read the file, so I'm not exactly having a lot of faith in that idea.
Also, call me crazy or perhaps I've just stared at it until it looked like ink blots, but in the hazy black stuff around the top, it looks like there's a thumbprint in the top right , and a bird flying away from the lamp in the top left.
I had opened it in notepad once before and thought nothing of anything inside, but this made me want to look into it again. As far as 99% of of what's inside nothing seems useful except an interesting date I highlighted. It reflects the 1987 of the LOG_test.
