Hey everybody, I made a #smell Civilisation as we know it is over. Laura Cornet, a student at the Design Academy Eindhoven in the Netherlands, has designed toys that let babies use social networks. They include a dangling mobile with soft Twitter and Facebook icons that your little bundle of joy can squeeze to post photos and videos, a squashable GPS tracker and cute booties that upload pedometer activity to Nike+. The project, dubbed New Born Fame, is intended to ask questions about our relationship with social media.

Fed up of dull health and safety notices? Just let a computer loose on them. Chris Callison-Burch of the University of Pennsylvania in Philadelphia used software to read blocks of prose and identify possible paraphrases.

The technique might be useful for turning dull public health guidelines into catchy jingles.

Sometimes you need a 3D version of yourself and you need it now. A kiosk called Shapify turns a body scan into a plastic “shapie”, rather than selfie, in minutes. The Artec Group in Palo Alto, California, hopes the booths, shown last week at an exhibition in Santa Clara, will be as common as photo booths.
