Thinking Outside the Box

This is a great example of thinking outside of the box. While browsing through images I wasn't sure what this was until I actually looked at it more closely. I think that it's an interesting play between architecture and typography. They make awkward letterforms but are still very interesting to look at. I've always considered words and letters on the sides of buildings but never thought to look up and use negative space to create the alphabet.
