Awww, this is cute — in an adorable cartoon supervillian kind of way. It appears that Dan Gilbert has an intricate miniature model of Detroit on the 10th floor of the Quicken Loans offices in the Compuware building. As Gilbert acquires more buildings, they light up, showing the expansion of his Rock Ventures empire. We're guessing Gilbert can be found here when he seeks solitude.
Head over to Curbed Detroit to have a closer look at the model.
