A UI involving selection and display from a library of videos, including a
"Mosaic" mode of operation, in which a primarily visual display is made
of information about possible videos, with the effect that a user might
select one such video in response to such visual display. The Mosaic
includes an two-dimensional array of entries, each of which has visual
information for that entry. The Mosaic collects relatively similar
entries near to each other in the visual field seen by a user. The focus
is centralized and emphasized, and has auxiliary information displayed
for further understanding. The array is dynamically rearranged in
response to change in focus and metadata about the entries. Relative
weighting of that metadata is responsive to user choice. The array
includes rows and columns each of which includes all possible entries,
but offset by relatively prime values.
