The mysterious colored wall in Huston

Huston we have a problem!
I found the two photos above at Flickr from @Hella's collection. She takes amazing pictures at Huston and other places.
I searched and found...
the wall... I have no idea how these photos were taken.
If anybody lives in Huston and know about this wall please leave a comment.
Thank you!
Have a colorful and happy weekend!
