One of the client projects I'm working on in the virtual world of Second Life involves generating different effects at different times of the (virtual) day. Second Life's virtual day runs six times faster than the real world's, and there are other interesting differences (the Sun and Moon move in unison, for example) so I thought it would be useful to make a reference movie to show what things look like over a complete cycle.
Let me therefore present One Day in Europa (57MB QuickTime movie), a time-lapse film of a static view from a parcel of land I own in the Europa sim. This reduces the virtual 24-hour day (4-hour elapsed time) to three minutes plus credits. If 57MB seems a bit much, there is a smaller version (23MB) available.
If you click on the thumbnail, you can see the information panel in more detail. The first line includes the number of seconds past local midnight, followed by that same number expressed in hours, minutes, and seconds; finally, the rightmost value gives you the equivalent time on a 24-hour scale.
