DateLens is an animated zoomable calendar for Pocket PC, supporting searching and planning tasks particularly well by using a fisheye representation of dates coupled with compact overviews, user control over the visible time period, and integrated search.
"DateLens focuses on the Calendar function alone - there is no integration with Tasks or Contacts, or even the ability to see them within DateLens. The interface as been described as 'organic' and I guess that's about as apt a description as any. Windsor Interfaces describes it as a "...fisheye representation of dates coupled with compact overviews" which is also accurate, but I think you really have to see it in action to understand what this means. I won't go into a big, detailed description of the interface, except to say that all the transitions are animated, so that you can really feel the drill down into greater levels of detail, or the sliding over of the weekday information to see what's happening on the weekend."
