From the developer:
Calendar applications for small handheld devices such as PDAs are growing in popularity. This led us to develop DateLens, a novel calendar interface that supports not only PDAs but a range of devices, from desktop computers to Tablet PCs. It supports users in performing planning and analysis tasks by using a fisheye representation of dates coupled with compact overviews, user control over the visible timer period, and integrated search.
You may want to check out more software, such as Book Organizer, MultiCalendar Client/Server Edition Client or MyTodo, which might be similar to DateLens.
