"Playfulness...tinged with gentle sadness,....there is humour there as well, ...and a willingness to be abstract."

I'm quite drawn to Distributed Network in the catalogue; it seems quite different from many of the works presented there and seems to have a great willingness to be abstract. You refer to post-minimalism in the catalogue (which is a "group" of artists that I love deeply; Eva Hesse, Robert Smithson, and Richard Serra are amongst my "heroes"!) and that makes sense in relation to that work in particular. 

I enjoy the playfulness in many of the other works, too.  Sometimes it strikes me as tinged with gentle sadness, which is perhaps one of the emotions experienced in care-giving. But there is humour there as well, which matters.
