Glowing glass

Art. Lebedev Studio sells luminous glass "Luminarus" . You take it in your hand - the lights come on.
The thing is interesting, but still not what you need. Some, you know, individualist. It is necessary that it works like this:

1. Pour into glasses.
2. The Toastman takes a glass and says a toast. The glass lights up. Moreover, the brightness may depend on the length of the toast.
3. Clinks to the neighbor and his glass also lights up. He passes the following and so on.
4. They drank - everything went out smoothly.

We get a device for friendly company. This is always better than drinking alone. :)

Upd: I wonder why the post has collected such a notable number of minuses? For Lebedev will remember? Or all for a healthy lifestyle? Or not to waste time on toast?

Upd: Glass produced by the company "Glasshayn." So this is not Lebedev’s own design studio. Apparently, he just liked the subject.
