The work on Anish Kapoor's Cloud Gate in Chicago's Millenium Park continues with six or so workers in Tyvek suits grinding and polishing-out the seams on the underside. I think this is quickly becoming the most photographed public sculpture in the world. I was skeptical, but it's really quite something. On the downside, the city has started renting parts of the park for private parties... hu? It is going towards operating costs for concerts and up-keep, but it's still a controversial move. Toyota reportedly paid $800,000 to rent the park for day in September. Grand Rapids own Rosa Parks circle is also operating largely on Corporate Sponsorship these days. Is this problematic, or a fine way to run city parks?
