Symbolism of Jess's breasts bouncing while she runs

This movie is filled with shots of Melissa George in a tank top sans bra, running and jumping and stopping short, with her fantastic breasts bouncing and jiggling.

Firstly, let this movie fully erase any doubts that her boobs are real, and they're spectacular. Second, it's obvious the directors intended her bouncing breasts to symbolize the bouncing time loop, therefore giving it artistic merit and not just something to ogle at for the duration of the movie. In this way, hitting rewind to watch them bounce and jiggle again is obviously an academic pursuit.😁
