We've all been sad, it happens to us all the time. I was sad just two days ago when BrickCon ended and I had to say goodbye to all my friends. But as you saw in Pixar's Inside Out, Sadness is an important emotion, that colors and balances our other emotions. Just ask builder nolnet, she's one of his favorite characters of 2015.
In mankind's never ending drive to recreate itself artificially, I suppose the inevitable outcome will be robots with less than desirable traits (hopefully murder will not be among them). Think about it, if we want our creations to have emotional characteristics like happiness, compassion and ambition, it stands to reason that they might also have depression, anxiety and anger. This robot by builder justin_m_winn has been nicknamed "Mel" because he tends to be melancholic. I don't know what his primary function is, but I hope it's useful enough to overlook his tendency to be down in the dumps.
My absolute love for Star Wars is no secret, I wear it (quite literally) loud and proud. I was nine years old when the film came out, the perfect age to be warped for life. It's what sparked my love of film, filmmaking, sci-fi, model building and so many other creative aspects of my life. It also sparked one of the first crushes of my young life, a certain strong-willed, no-nonsense princess who defied an empire and saved the galaxy. I'm deeply saddened by the loss of Carrie Fisher, my heart is broken.
