The Clock of the Long Now project is a really interesting way to think about time in design. (http://www.longnow.org/projects/clock/). In a similar way, a sunlabs research project called Celeste may provide a way for us to think about mutable object stores in education that live on a distributed set of devices all over the web which provide a persistent memory archive for our digital records.
I'm looking to fund a small collaborative community with our pioneering librarians and archivists to investigate it's potential. I should have the proposal together for Glen shortly while also posting a community on Education Commons for those that may wish to track it's development.
