By 2020 there will be 24 billion Internet connected things on the planet, most of which won't have a screen. Web designers and developers are uniquely placed to play in the physical computing world.
With skills in information design and working with numerous technologies at the same time, the skills of the web practitioner are directly transferable to the Web of Things and are leading much of the exploratory work occurring around the world right now.
Lots of examples of Web Things in the real world as well as live demonstrations (links to projects for slide share viewers) should inspire viewers to get started with the web of things.
** Note there is a momentary audio drop out just prior to 4 minutes into the presentation. If you skip ahead to the next slide you'll regain the audio (about 25 secs of content missing).
Clipping is a handy way to collect important slides you want to go back to later.
