Ask HN: Next generation of responsive templates, interaction with webcams?

Nowadays, we can see big changes in responsive templates and new requests to completing that, more smart and fast.

Well, now, we have good support of webcam API(s) in browser and JavaScript, so I think the next generation of responsive templates will have interaction with webcams. For example detecting the brightness of the environment and then change the background and text colors to something better to improve the readability of the page.

What you think?
