I was checking out a really cool open source project tonight called slides where you can stitch HTML and CSS pages together in a slideshow experience that works cross platform. They work on mobile and tablet devices (even supporting touch screens and full screen). And the slides are stored online but can be displayed offline too! They also sync with Dropbox and can be shared as I'm doing below!
This is a nice, concise slide by Jamie Cavanaugh that explains the difference between Interaction Design (IxD), User Interface Design (UI) and User Experience Design (UX). The analogy of cereal, bowl and spoon from Ed Lea is ingenious.
