Remember the floating training remote in Star Wars? Some people have done DIY versions of the remote that can levitate on your desktop. However, leave it to NASA to create the real thing and call it SPHERES: Synchronized Position Hold, Engage, Reorient, Experimental Satellites: robotic bowling balls (OK, 18-sided polyhedron satellites) with autonomous propulsion, power, avionics, software, communications, and metrology subsystems, that fly freely in the ISS. First tested in 2006, they have been upgraded with Android smartphones, which makes them (for now) the less terrifying item in Google's growing robotic arsenal.
Paper Matrix is a blog that gives instructions for cool papercraft objects, "reinterpreting the Danish tradition of woven paper hearts and ornaments."
