We're putting together a presentation with a lot of data for an internal "project review", where we meet with various people in the organization, present a status update, etc.  As part of that our concept artists do some drawings to reinforce or illustrate some of the concepts that are only presented as words (typically for new features or significant unit lines coming up).  Sometimes we get in a kind of cycle where they are doing sketches and we're giving feedback and they send updated sketches in near realtime. 

I can't draw to save my life, and it just blows me away what these guys can do.  I wish I could share some of them with everyone here (someday!) ... but watching them just bring these images to life and change them around so quickly is just awe-inspiring.  It really is one of the purest expressions of the creative form, making something from nothing.  That's something I enjoy a lot when programming but it's so abstract compared to what our artists do.
