The Prism

Last Year, 2013, saw the 40th anniversary of the Pink Floyd's legendary album, The Dark Side of the Moon. The iconic album cover design by visual artist and band's friend Storm Thorgerson is forever remembered as one of the greatest album cover designs in history.
The prism and rainbow have now become the symbol of the band. It is simple yet impressive and meaningful. It is the visual representation of the subtle meaning behind the album's title, the dark side of the moon. It is about mental illness and lunacy. (based on Storm Thorgerson's interview in Classic Albums: Pink Floyd - the making of "The Dark Side of The Moon")
Now, let's take a look at contemporary visual artists' re-imaginations of this iconic design.

These are my favourites:

The Pyramid, probably the most famous triangular-shaped building in the world.

The prism design takes on Yayoi Kusama's style.
