A case with a battery that plugs into the phone to give it extra charge.
The case would have LEDs like those things at restaurants on both screen side and back side.
When the phone rings the lights would flash. On both sides.
It could even have a vibration motor or several in it that could vibrate in different patterns.
The lights could flash in different colors and patterns to denote specific callers, texters, messages, etc.
I imagine there is something out there like this already but geared more for hearing people.
This could be geared for deaf people.
