In a time when we are barraged with a thousand and one ways to save the planet, the elegant and uncluttered ones always win our hearts. For example, with regards to the problem of space shortage/homelessness, perceived or otherwise, Jin-Hul Kim’s low-tech but portable Space Book just amazes. It offers space savings by, what else, popping up to reveal life-size furnished spaces.

Of course, it’s yet a novel idea but the possiblities are endless — pop-up toilets, pop-up brothels, pop-up shopping malls, pop-up main battle tanks, pop-up anything, pop-up ****. If they can do hurricane-proof Space Books for New Orleans, that’d be cool.

On to the next concept. While the above is a space-saver, the Rainbow Book below is one hell of a pop-up book that will waste your time. Give your eyes a break from the monitor and flip a Rainbow Book. It’s actually a flip book but kindof pop-up too since when you rapidly flip its pages, a rainbow kindof pops up.
