The runes they use have a much deeper meaning to the context of the film. the R one Raidho or Rad symbololises the personal journey and our inability to communicate it to others. the arrow is Tyr or tiwaz which is symbolic of the Norse God of battle, the one that looks a bit like an eggtimer is dagaz, it symbolises the daily cycle, Othila the one that looks like an upside down fish, is about recieveing spiritual inheritance, The double X symbol we see on the yellow circles is Inwaz or inguz symbolises unity, and harmony, but it can also symbolize the love between two partners, an undying bond. I haven't seen this film yet, but all of these runic elements seem to tie into the storyline complicitly.
