ArtPrize has been happening for the last 5 years in Grand Rapids. Artists from all over the country, and world come to show off their work. There's usually around 1500 pieces that get set up all around the city (outdoors, in restaurants, offices, pretty much everywhere). It goes on for 3 weeks, attracts 400,000+ people. Its real cool, if you're going to be near Grand Rapids in the next few weeks, come check it out. Plus $560,000 in prize money up for grabs to the top 5.
Anyways, here's a quick little edit I made yesterday before everything officially got going.
