This concept wants you to smell it, smell it, Smellit

We admit it: this could just be another highfalutin gadget render that'll never breathe the polluted whiff of day. But it's a nice render, which demonstrates a concept called the Smellit: a miniature olfactory factory that's meant to connect to your PC and bring a "fourth dimension" to video and gaming. Its creator, Nuno Teixeira, even claims he's found a French company to build the device and show it off at the Lisbon Design Show next week. Now, the principle of a practically-sized scent generator has already been demonstrated by others, but we won't be convinced until we have to open a window.
