Show HN: Windtalk – Let windows/iframes invoke each other's functions or objects (pshihn.github.io)

Wow cool. Just wondering though, how is this even possible? I thought Iframes were sandboxed from each other for security

I'm using a proxy object that ends up sending messages to the iframe behind the scene. So, from your perspective you're just accessing the object/function as if it is was in your window's context
