Origami, the ancient japanese art of paper folding, might very well have a purpose in the future of mobile devices such as cellular phones.
A problem faced nowadays with technology getting smaller is fitting a large display on these small devices. To circumvent that problem, Inventables are developing an origami based folding technique to expand or fold the screen of a cellular phone or DVD player as the mobile device is opened or closed.
I am eager to see whether or not this technology will be used. For my part, I will be waiting for the holographic display ;)
