3Doodler - The world's first 3D printing pen

Here's some cool 3D doodles I came across on their Twitter feed: + + (Van Gogh!)

I really like this - you can take your drawings to another dimension (literally). Would make a great Christmas present for doodlers!

I had a chance to play with http://www.creopop.com the other day and it is pretty cool. CreoPop is different as it prints with cool ink so you can print/paint on human skin, have aromatic inks etc. From my conversations with developers I understood that the killer real world applications will be soldering 2.0 with magnetic and conductive inks.
