Have you ever been in a conference or at a performance when someone’s cell phone rang, even after the emcee asked for all phones to be turned off? I have, and it is nothing short of annoying. But there is hope!

NaturalNano has developed a paint product that can solve the problem.

In a combination of a specially formulated paint and wireless technology, they can control which radio frequencies are available and which are blocked and which are available. At intermission, access can be allowed for cell phones, then it can be “switched off”.

It sounds like they can allow WiFi but block cell phones as they choose.

At last, a solution to the new digital etiquette problem.

Thanks, Paul.
