OK Go Poster
This easter egg can be seen in all versions of the movie.
Throughout the movie, when Clare is seen living in her original house, on the walls of her room are a number of different artworks, with most being paintings by Clare herself.
If you look closer however, fans of the American rock band, OK Go may recognize a familiar scene buried among the paintings. For their third album, “Of the Blue Colour of the Sky” which released in 2010, OK Go made a music video for the single, “This Too Shall Pass” where at the end the band gets shot in the face with paint cannons. This is the scene found as a poster in Clare’s room.
The poster itself appears to be custom made by the studios art department, as no posters with the unique lettering in-front of the band can be found anywhere online for purchase.
