Waves on the outside

It's rare to see graphics as part of the exterior of building walls. So when I saw this building near the edge of town, I knew I had to take a photo of it. Plus, coming from a graphic design background, the use of design creates room for thought about design as 'identity'. For some strange unknown reason, I had a feeling the building was a gym, but I was wrong... although now I don't remember what it was I saw when I peered through the window. I think it was a shop... or maybe... mmm... my bad memory... =[
