For many years, long ago, I did a similar project called One Minute Vacations, archived here: https://www.quietamerican.org/vacation_1.html

There are about five years' worth, organized by year; little album covers function as tabs of a sort.

Quite relaxing.

> Your scene should be filled with many layers of activity without any dominating elements.

My one feedback would be to show me an example of a few images where there is activity without one dominating element

Very nice, shows different parks for 1 minute
