These are the slides from the talk I gave at MIT for Larry Rudolf’s 6.964 Pervasive Computing Class.
	The talk describes ongoing work in my department at HP Labs.  The title includes a reference to the “Cooltown” project, a name we used until recently when HP began using the name as part of its brand.  We’ll probably come up with a new name.  Or not ;-).
	In any case we plan to continue working on the idea of physical hyperlinks, technologies that support them, and ways of leveraging them.
