Response Point in Comics?

I was fiddling around with clip-art in Power Point a little while back, and put together some comic strips to illustrate some ideas.  I figured the same technique could be used to demonstrate some Response Point concepts.  Here are some first attempts.  They could definitely use proper pictures of RP phones, etc, and lots of polish.  But aside from that, what do you think?  Is this useful?

(Off topic, but speaking of comics, I just finished reading Bone.  Yeah, I’m a bit behind the times.  It’s as good as they say it is.  Get the ones published by Scholastic/Graphix – they’re in color.)
