Just a picture This is made with existing colors and parts, so it could be built in real life.
I played the Joust project that @colinmacc shared a bit ago and decided to thank him for porting an awesome game by making his profile picture out of Lego pieces. Obviously, not every detail was able to be gotten (for starters because it's a 2D image, and secondly that it's pixelated), but I'm pretty happy with how this guy turned out.
