Polite Umbrella
Polite Umbrella, from designer Joo Youn Paek, is a shrinkable umbrella that enables users to morph its shape in order to reduce occupied space and to increase user maneuverability. Users can easily adjust their umbrellas anytime by pulling a handle so that they can protect themselves from harsh winds or bumping into others.
I love this – reminds me of this New Yorker article about umbrella design: http://www.newyorker.com/reporting/2008/02/11/080211fa_fact_orlean
