I must admit to not knowing what a brailler was before reading the Dexigner article. A brailler is a device that blind people can use to type in braille. An iconic and ancient one has recently be redesigned and I think it looks very robust and usuble. It also looks very friendly. It still amazes me how people can design a functional object that looks friendly. 
A decidedly unfriendly object is James McAdam’s Safe Bedside Table, a small table that doubles as a club and shield to defend yourself.
Some people say that 3D printing is like ‘growing’ objects. I would dispute this, Tokujin Yushioka, he grows things. He grew a chair consisting of crystals. The production process seems to be a bit slow for Shapeways but we should consider it.
