An amateur animator going by Enquaynay on YouTube created an awesome, hand-drawn version of a cutscene from Portal 2. Even cooler, they reimagined the game by turning robotic characters Wheatley and GLaDOS human. As a fan of traditional animation, I find it incredibly impressive for one person to do this much quality work.

You can watch the video below. You can also check out some rougher Wheatley stuff here.
