Sad! I really enjoyed going to the Kusama exhibit with my (now) wife years ago, and my daughter had a Kusama phase when she was about 5 years old and dressed up like her with a hot pink wig and polka dot outbit.

Highly recommend watching her speak, for instance in the below interview. I've found her to be very eloquent and expressive verbally too.

No.

Such an awesome figure.
