Seeing through time
[Peter Langenhahn](http://www.peterlangenhahn.com/content.html) makes [cool photo composites that combine lots of separate moments from a single event](http://www.youtube.com/watch?v=0HBn7TMWf7k).
[Peter Funch has done similar works](http://www.peterfunch.com/index.php?/ongoing/babel-tales/), based around themes of people passing through a place.
Before digital cameras were common, I did something like this by cutting up prints and gluing them to boards. Kinda feels like you’re seeing through time.
