Museo Nacional Centro de Arte Reina Sofía

One of the entryways to the Museo Nacional Centro de Arte Reina Sofia in Madrid, Spain

I loved the roof, this just doesn't do it justice.

The entrance to the exhibit by Yayoi Kusamai that spanned a very, ah, eccentric life

Yayoi Kusama's light installation.  This room was so amazing I couldn't pass up the chance to photograph it.
