My only source is my business partner, but it's a pretty good test. At 10-15 feet, you can only see features as geometric shapes, but on very well-designed sites you can probably tell what you're "supposed" to do. This is most effective for signup and purchase flows, where simplicity matters most, but I think it can lead to insights on pretty much anything.
