Pepper and Carrot is created by David Revoy. He works pretty much exclusively with free and open source. He has done a number of projects with Blender as well. He's quite the exceptional artist, and his videos are lovely.
He has great time lapse videos using Krita on his Youtube channel -- https://www.youtube.com/watch?v=Hr7OPBxh5_o

Even translations are community driven :)
Disclosure: I'm just a reader of P&C, who found the comic not so long ago and fell in love with it!
