Some of you may remember thread about hiding information in an image started by a sadly clueless student. Well, here is something related:

Computer science news on Phys.org
Basically it has an interesting histogram.
 
I GOT IT! Haha, that's pretty neat.
 
Wow - that's an amazing trick!
 
I don't understand what is hidden... the NYC skyline? If so it's not hidden in the image very well it was the first thing I noticed which is why I kept staring thinking I'd notice somtehing else haha... but nope. Maybe someone can give a hint or something idk
 
I see how it can be a histogram but there aren't any numbers associated with it. How do you make sense of a graph without #?
 
Nice histogram!
 
Its all in the histogram
