An interesting example from John Maeda. Applies idea of an "infinite zoom" to a timeline as the viewer can dive seamlessly into a timeline.

I find this an instructive demo into how a seamless interface, which to me promises a consistent sense of orientation and a dynamic quality, can also produce the opposite effect. The fact that looking at years, months, days, seconds in precisely the same way seems to have a "flattening effect" where all time units look the same, and what first seems quite dynamic feels at the end quite static. Also suffers from / enjoys the benefits of being a "content-free" demo; presenting a very elegant solution while avoiding any of the meatier issues that would arise if one were to try to present actual information in this model.
