I found two long but very interesting videos which delve deeper into the event and the broad range of responses to it.
What's clear is that big questions have been raised on all kinds of levels (not just about art) and more importantly they are being asked by almost everyone in the community.
The first video is a kind of three person panel, centered around the project's founder and original funder, Rick DeVos but most of it involves questions from a very engaged audience. (can't seem to embed video,follow link)
All kinds of topics are touched on in this video but generally most are art related.
Few "formally trained "arts professionals" like university faculty, arts administrators, curators and the like had ever dealt with the energy level and passion this thing brought out.
It's also very clear that Rick pushed this snowball in a downhill direction without almost no idea how big it might get or what it's final results might be. He knows it--and that's what's so great about it.
Museums, local venues of all kinds, Businesses and the city government were forced to actively collaborate with each other(and more than a thousand artists) in a short time frame with scarce resources or risk a spectacular public failure.
PLEASE WATCH, I really think it's worth it.
