While browsing through a "Retail Archaeology" video on YouTube (they document dead or dying malls), there is an interesting clip where they are in the dead Tanger outlet mall next to the I-10. They stumble across the Phoenix Mart office and information center, which is only occupied space. Features a model and description, though I assume the project is closer to the dead mall in the video than reality.
Phoenix Mart starts around 23:10 in the video.
