42 has a good article with pictures of the arena up over at BSS.
The New Orleans Pelicans held a Select-A-Seat event at the New Orleans Arena today. We used this opportunity to peek behind the curtain and see the renovations. As noted before (generally, and via blueprints), the Arena is getting some serious work, to the tune of $50m. The inside and outside will be changed. For those who will ask below: No, it will still have the green skin.
All of the changes this offseason were on the interior, and some were in areas that most fans will not see, such as the locker rooms.
