I may be wrong as it is just a pic, but that looks like a complex use of 3d box-pleating techniques. Like the kind used to make Mooser's train or implement cubes (waterbombs) into a model (like Hojyo's Thunder God). I have done something similar, but not quite the same-I only had individual cubes popping up, not complex raised patterns. Looks really cool and well folded though.
Jonnycakes, I don't think it's box-pleated, though I've never actually done box-pleating, so perhaps I just didn't realise that's what it was! It's actually fairly simple to do, but kind of hard to describe...I could try making a video of the step if anyone was interested?
Boxpleating is anything that uses only horizontal and 45 degree angle folds. This doesn't include shaping/detail folds, so I guess there is some leeway in what is boxpleated and what isn't.
I don't recognize it, although it's possible it could have been folded before I started folding tessellations. It doesn't look like the kind of stuff people were doing back then though, so I think it may well be an original work. It looks very nice, I'm going to put it on my list of models to reverse-engineer one of these days.
