I was writing a post for my company's blog talking about Open source, and wanted to wrap it up with `Let's make waves`.

I was pretty sure that the expression meant something like *Let's replicate this, and amplify it in every new replication*. Like the fact of doing something small but nice, so others join, do something else that's small too, but summing all that you end up with something big.

But a couple of colleagues told me they didn't know that phrase at all, and I couldn't find any reference to it myself.

Have I made that whole definition up from nothing? Is it a known expression? Could I have translated it from another language?
