The wall cover, I find to be more simple then 'boring' in the sense that it isn't busy and portrays underlining symbolism. The thing is you could simply glance at it and think: "a wallon the cover of The Wall. Ha" or you could think "Wow this wall of "The Wall" is a simple and mystifying symbol of the lunacy and barrier that a helpless mind is needs to create in order to protect himself from the outside word and society. Something to shield the mind from the horrors of life, of war, of cheating wives and over protective mothers." Really you could keep from thinking about it but its art and just like poetry, you need to dig deeper. I can tell you it took me longer then a few moments for me to figure out the whole story behind it. Also if you aren't familiar with the album its an even bigger mystery that could be even more enticed by it.
