I understand what you mean by unusual exhibition because it does look very unique and would never thought of something like this. But thanks for opening my eyes and making me aware of more outstanding things when it comes to patterns and exhibitions:)
I think we're not alone with this. And the sad part is that not many can see it as interesting or see the value in it.
When i bought the ticket, asked the lady what can I see today. She told me the title of the exhibition, but enthusiasm was lacking and saw no joy on her face. However, if you look at it from a different perspective, from the creator's point of view, i think you see my point :)
