|"The idea of the prism came from a series of conversations with the band, especially with Roger and Rick. Roger spoke about the pressures of touring, the madness of ambition...and the triangle is a symbol of ambition. Rick wanted something more graphic, less pictorial, something, as he put it, more stylish than before. Floyd's lighting show was regarded as very powerful and the prism seemed a good way to refer to that, and be more graphic at the same time."|
"A larger physical representation of the triangle was the pyramid...perhaps it could be seen as a testament to madness, more 'vaulting abmition.'"
