Many years ago I saw a number of Mark Rothko's paintings in an exhibition in London somewhere and was amazed at their visual impact (you don't get the same effect looking at photos of his work). Every day I walk past a boarded-up building and this particular panel has a large rectangular blob on it that, every time I see it, causes the thought "that looks a little bit like a Rothko painting" to pop into my mind. This is a (probably futile) attempt to exorcise the thought...
@janturnbull@annied@simonpz Thank you all - at least the thought I'm getting now is "that looks like a Rothko - and some other people think so too" ;-)
