Talk about cool!  It’s a 3D pen that lets you draw objects in the air.   A Boston company called Wobbleworks has created what it says is the world’s first pen of it’s kind.   You plug it into an electrical outlet and it works kind of like a glue gun.  It oozes heated plastic which quickly cools and solidifies, allowing you to build any kind of design.  The company expects to sell the pen for about 75 dollars.
