Everything in reverse! 

- songs (like 'sinking in reverse' by eaneikciv)

- texts (letters, words, sentences, does the reversed text sound better?)

- videos (like FROZEN by DavidJfulde)

- concepts (love in reverse, flight in reverse, birth in reverse)

The way I see it: we can tell a story (or observe a process) in two ways: from beginning to end and from end to beginning. Sometimes going in reverse reveals a lot more than meets the eye. Just a thought. :)
