User studies and intuition both suggest that the activities that a knowledge worker engages in change—sometimes dramatically—over time. Projects and milestones come and go, and the tools and information resources used within an activity often change over time as well. Furthermore, activities completed in the past and their outcomes often impact activities in the present, and ongoing activities will, in turn, affect activities that will be undertaken in the future. Capturing activity over the course of time has long been a problem for desktop computing.

So does polychronicity scale? Or is it a nested phenomenon whereby someone might be monochronic within hour- long intervals but polychronic when the frame enlarges to a month? And if so, what might be the consequences of different nesting combinations?

4.3.3 TimeBotsWhile the Printer Clock focused on emphasising the embodied and situated nature of time, pointing to the mesh of activities and characters that come together to create time, the TimeBots drew attention to personal rhythms and how they played out within the context of the classroom. The aim was to challenge the idea that the world is in a state of constant acceleration by inviting children to reflect on the multiple speeds of their day. In contrast to the slow movement, which assumes acceleration as a universalised condition and attempts to counteract this condition by promoting opportunities to slow down, the intention here was to invite the students to explore the variant speeds at which they l
