I have a nice pop-up book of the Gaudi Cathedral in Barcelona. I've seen more & more pop-up books in museums -- the Metropolitan Museum in NYC might have some. (For those of you who've never seen this cathedral, it is worth a visit just to see this incredible feat of pre-computer engineering. Hint: the building was designed upside down with weighted ropes.) I've also seen more & more pop-up greeting cards recently. http://en.wikipedia.org/wiki/Pop-up_book Due to the popularity of the pop-up greeting cards, I expect there to be an explosion in new designs & innovation for this form. With ubiquitous laser & ink-jet printers which can print on cardboard, it would be easy for one person to design some really cool new pop-up ideas. Perhaps some of you on math-fun will be the first!

What's the biggest pop-up any of us has seen in a pop-up book? What are the mathematical or physical limitations on what a book can do when you turn a page?
(I should probably just ask Eric Demaine, but it seems like a fun enough question that I thought I'd post it in this forum and see what people come up with.)
