How can I demonstrate that the same wireframe can be used for varied visual designs?

I'm trying to demonstrate to someone that one wireframe or template can be used across multiple brand experiences (we want the UX to be similar, but the brand experience to be different). At some point in the past, I found an article or blog post that showed multiple examples of "one wireframe, two/three designs", but I cannot find it any more. Anyone know of any resources - either actual websites or articles/blog posts/portfolios that demonstrate this?
