I checked two of my domain names (MultiForums.com or Loan.nu) currently parked using Google Adsense for Domains. I saw three different templates, the standard blue text link color, blue text link color (centered), and the new template Tulip flowers with light blue background. I'm hoping to see more templates for parked domain soon. Here's are the captured images.
Let me know if you see the same parked pages, simply refresh the screen to see the different templates.
