For the last 15 years or so, I’ve been going round telling people that in Sweden, it’s illegal to advertise to children under the age of 12. I’m not sure if it’s true, but it should be true.
This is a useful idea waiting to happen though I think. A web-enabled “thing” analyser/recogniser. The first possible uses that spring to mind are medical (and no, I wasn’t thinking that you’d never have to visit a VD clinic ever again. What is it with you people?)
Another possibility is a home scanner like this, which could automatically upload a scanned object to a print-shop’s 3d fabber, which could then be delivered back to you as a physcial object the next day. Ok – that’s kindof a long-shot, but you get the idea. It’s got to be useful for something. Well, something else.
