Back in 2005, I trained with Entheos in their animation program. Lacking the patience and the skill, I had no intention of becoming a full-time animator, but it was a long-standing dream to learn the trade. At the end of the program, I even took part in creating a short clip.
Now, four years later, I'm happy to see that the guys have come a long way.
By the way, there are a few more nice clips from the group (and a few groaners.) Check 'em out.
