This might not have anything to do with movies, but it deserves a mention.
The collaboration of three companies, namely Microsoft OneNote, the Collective Project and Limbitless Solutions changed the life of a 7-year-old boy. Instead of just making a typical, functional limb they went all out and really brought a piece of Iron Man to life. To make the moment more special they asked Robert Downey, Jr. to present the 3D printed bionic arm, inspired by the actual Iron Man suit design, to the new, real life Iron Boy called Alex. Downey stated on his Facebook page what a honor it was to be there.
