I went to the one in San Mateo, CA.
It was interesting but 50% of it is alternative art similar to what you would find at “Burning Man”.
In other words...Uber Liberal and Obummer’s Base.
I went there with my family. You're right, most of it was glitzy art for entertainment's sake. My granddaughter enjoyed the huge bubble wands to blow bubbles, and the light shows in the darkened cavernous building. I went to find stuff to help with my 3D print hobby but came up mostly empty.
