what i like about this clock is the ability to visualize time. i'm aware of factoring in time when thinking about a task. sometimes starting a new task depends on what i'm doing at the moment. buying a bottle of water may take me 5 minutes, but getting there & back adds 30 minutes. & the thing i'm working on now takes another 15 minutes. & i have to get to class in two hours. to get my water i can catch the bus in 15 minutes or the one at 45 minutes. i'm constantly tracking time making decisions about all that. SpriaClock seems able to visualize all this. it helps me visualize what may be happening with the red + blue astroschyzy numbers. from SpiraClock: A Continuous and Non-Intrusive Display for Upcoming Events (pdf) by Pierre Dragicevic & Stéphane Huot:

ABSTRACT In this paper, we present SpiraClock, a new visualization technique for nearby events. SpiraClock fills a gap between static calendar displays and pop-up reminders by giving the user a continuous and non-intrusive feedback on nearby events. Events are displayed inside an analog clock that can be used as a regular computer clock. We used SpiraClock for displaying bus schedules, and collected user feedback.

INTRODUCTION Software organizers all have global and static calendar displays that are useful for building, organizing and consulting schedules. However, they can't be continuously displayed on the screen, and accessing them has a cost. Users consult them at intervals, and have to rely on their prospective memory — or external artifacts such as post-it notes — for performing the right tasks as the events are becoming current[1].

Most organizers additionally provide customizable reminders that pop-up a given amount of time before the event actually occurs. Those reminders are useful but intrusive and do not allow the user to anticipate events in a natural way. For example, as an event is approaching, the user will typically have to make decisions on which tasks to perform, including completing his current work or starting preparatory activities related to the event. Pop-up reminders are not suitable for such continuous time management tasks.

The SpiraClock visualization technique we present in this paper allows the user to anticipate upcoming events in a natural way. It gives the user a feedback on nearby events by displaying them inside an analog clock that can be used as a regular computer clock. SpiraClock uses a continuous spiral display and takes advantage of people ability to monitor time without interrupting their tasks.

SPIRACLOCK VISUALIZATION AND INTERACTION TECHNIQUES SpiraClock is an analog clock with a white spiral inside representing the near future. Events are depicted on the spiral as colored sectors (see figure 1). Events in decreasing imminence order are read clockwise, starting from the current extremity of the minute hand (i.e. present time). Sector edges coincide with minute marks according to the event starting and ending time. Events occurring in less than one hour can therefore be directly read on the outer branch of the spiral. Besides, each further revolution of the spiral shows events of the following hour. As time moves forward, the spiral unwinds and event sectors move in a radial way (see figure 1). Events are highlighted as they come closer, eventually fading out when they cross the minute hand. [+]

found this googling for a small LED clock to embed into a CD cover. my idea (actually, my brother kinda gave me the idea) is to create a CafePress CD booklet & list all Astroschyzy cycles for a season. i'd just list the Bonorum info. thinking about how to effectively organize that graphically — it'd help if a clock displaying Universal Time could be embedded somewhere. mentions SpiraClock here, somebody else briefly describes it here & was also presented at CHI 2002.
