This innovative design concept is by Yi Fan & Honh Yih Chu is called the 'Tandem USB' and it conveniently allows multiple USB devices to be hooked up together to one port, without any cables getting in the way of each other. The Tandem USB connector is already being acknowledged in the design community, it has won a
iF Concept Design Award in 2010.
I would definitely find myself using this USB centipede, considering the lack of USB ports my notebook has. Its unfortunate this is still a concept.
