Update on this: the art camp she did this summer was interesting to observe. This was a group of kids who were very self-selected, obviously--who wanted to do a two-week art camp. They were strong technically. DD was one of the weakest ones technically, although also I think one of the youngest (I have a hard time telling age, though). She produced some "enh" stuff, some fine stuff, and then a couple of things that were rather astounding--not, again, due to technical skill but due to originality of vision. The teacher seemed to be quite good, but there was again the emphasis on cool materials and constant glitzy "neat" projects. Very jumpy--new thing every day.
I wish I could say I'd seen her doing more art since, but not so.

I really hope this doesn't fade away. I do think she is just so focused on what other girls her age are doing. Like you said, HowlerKarma--unicorns and name art. ergh.
