(keitai-l) NEC 'tactile echo'?

Hello!
I'm looking for a certain phone -maybe you can help me.

"A recently phone released by NEC features a button for a 'tactile echo' of
the phone: When the button is pressed, the phone will vibrate in a certain
pattern, depending on its state (short vibration = nothing happened, two
short vibrations = text message, one long vibration = missed call, etc.)."

Somebody showed this thing on CeBIT trade fair to me, but I don't know which
one it is, and I can't find it on the web. Did you ever hear of that one?

Thanks!
Fabian
