I was hoping to learn why the pixelated designs started appearing. Author says they work; but what led anyone to think that those designs might work? Why did they try them in the first place? And actually, why do they work?
I find it bizarre that this is all done by private companies, competing in public competitions, with royalties to be paid for the chosen design. And I'm quite surprised that some designs were found wanting because they don't work under IR (e.g. the soldier shines against the background). That sounds like they're using the wrong dyes; surely a decent design methodology would lead to such problems being remedied by incremental improvement?
