Well IMHO the oposite is more interesting, to vibrate with as less
noice as possible :))) But when the one is possible, the oposite
of noise should be possible, too. ;)

And also different vibration pattern would be usefull to have the
Neo inside a pocket and have short and clear signalisation for
- incomming call/sms/email/... (important - not important)
- go right left
- you are in time - you have a delay - go faster to fetch the train
- time (1/4 1/2 3/4 1/1 hour signal)
- reached a tagged location
- a communication partner becomes reachable
- ...
