Jude made a comment on my last post about stretching grids - and that suddenly awakened a memory: Shirazeh Houshiary's east window for the church of St Martin in the Fields in London. There are several photos of the window on her website, under site-specific works. This pic. is from there.
It is just such a simply beautiful, appropriate work which says so much with so little - and yet leaves room for pondering and ambiguity. Speaking of which, there is also an interesting TateShots video of her talking about her work here (not about grids).
Indeed, I was only thinking about this artist this morning over breakfast as I read about her sculpture in the latest Sculpture magazine.
