Hand-animated v computer-drawn

An interesting thought is why are hand-drawn images often more engaging than computer-drawn?

This cannot always be the case, otherwise we wouldn't be wowed by films such as Pixar's Toy Story 3 and Up, and how realistic they look. Although these still maintain a cartoon quality, perhaps unlike Avatar with which I didn't really engage.

But there is a something in it, that the rougher something is drawn then it often appears more engaging, more human. This article got me thinking. I suppose I wonder how it applies to images I may use in my work at school, and in any graphics I use in sermons and talks.

I wish I could draw!
