California-based Lego artist Matt Armstrong (aka Monsterbrick on Flickr) has been creating amazing brick works for decades and works in an eclectic range of styles.
He works as a martial arts instructor in San Diego, but when he's off duty he's furiously building stuff with Lego. Armstrong recently showed off some of his latest creations at Star Wars Days at the nearby Legoland. They included this colorful take on the astromech droids of "Star Wars" such as R2-D2. This one is called RU-KRAZY.
