Stefan G. Bucher is an artist and illustrator who turned a blog about drawing monsters into a great video compilation and an interactive project. Visitors to the site created names for the monsters, as well as stories about them, which they posted in the comments for each entry.
Many of the videos go beyond ink-on-paper drawings into animation. Originally, this was a personal art project for Bucher, to see if he could find a way to motivate himself to do more drawings. Eventually it turned into a book (with a foreward by Ze Frank) and lots of media mentions.
