Researchers from Canada's Queen's University's Human Media Lab developed a new morphing smartphone concept that can change its shapes to give notifications without any noise. The concept uses a flexible e-paper display made by PlasticLogic. This is just an early prototype, and the researchers estimate that it will take 5-10 years to commercialize such technology.

Earlier in 2013 the same research group unveiled the PaperTab - a flexible paper-like tablet, based on Plastic Logic's 10.7" flexible touch E Ink displays and Intel's Core i5 processors.
