A technique for managing and representing dynamic context information. The system can manage local and remote activity information including sensor and computer application generated events such as calendar reminders. The technique allows users to store contextual relationship information associating an activity stream with temporary changes in the user interface that lie just outside a user's focus of attention in dynamic stylesheets. The dynamic stylesheets can be applied across work groups or companies and provide a similar contextual work environment. The dynamic stylesheets can also be customized to the specific needs of an individual. The techniques can be expanded beyond the computer desktop focus to include a user's complete work environment.
