Good news, New Yorkers. There's a new umbrella in town that is sure to help sidewalk rage during these rainy days we've been having. Aptly called "the Polite Umbrella," you can shrink it on either side as other pedestrians walk by. In the designer's own words, it's "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." There's a demonstration in a video on the site, but no info on where to buy it! So, keep stabbing each other with your non-polite umbrellas we suppose. NewYorkology has more New York-centric umbrella options, but none quite as polite. [via Kellas]
