This is a fantastic and ambitious project by Illustrator/Animator Andy Martin. I just can't believe how much thought and effort he has put into this.
Every day on his blog Illustrated Aliens, Andy uploads a new character illustration that will inhabit a planet. At the end of each month he releases an animation about the planet that involves the characters he has designed, and a print of the planet and characters. Each animation has it's own theme and message that reflects the characters design.
