Looking for an Example of Interferometry to Illustrate Increased Resolution

I'm looking for a non-mathematical example that pretty well makes it clear that interferometry increases resolution of an object. Something tangible would be useful. I'm thinking in terms of its use in astronomy. For example, and I have no idea of this is workable, use a water tank and produce waves from two sources, then perhaps somewhere on the combined wave fronts there is something that might illustrate this point. Slinkys? Vibrating drum surface? Commonly available lasers? Simple mirrors and lenses?
