Many of you may still not have seen just how amazing the creations that can be got from rapid fabrication devices are. Lots of fabricaneurs have been busy placing designs on a service called shapeways (VC funded by phillips.
People have been making and sharing all sorts of things, this trackball assembly (more here in how it works )
They have also of course been exploring the entertainment side of things. Such as this killer flower character
With an increasing number of people making devices, small devices for a smartplanet, some interesting cases for the various sensors, monitors etc can be created using this technique. Low cost low volume is also very handy in a downturn for prototypes.
i heard about this technique a few years back, it really does hold great possibilities for the future.
In the last couple of years several other similar sites have been popping up. Plus this latest mess with the Penrose Triangle is really interesting.
