Prosthetic extensions to replace or enhance damaged or aging human body parts are becoming not only more commonplace but far more advanced – even without the use of anything more complex than mechanics. Lisa Bufano’s dance routines are full of leaps and bounds thanks to her springy replacement feet, and if you can afford a set (and wait for him to make them) Dan Didrick’s X-Finger prosthesis provides the ability to grip to those who have lost their fingers – if you have $11m to spare, he’s in desperate need of investors, by the way. It turns out Futurismic even has a cyborg contributor – essayist and foresight consultant Jamais Cascio got BoingBoinged for this story about his new hi-tech hearing aids.
