Buddha has set a Vinaya rule for monks against public display of
supernatural powers (even though this Vinaya rule has been broken
many times before, even today).
If it were not for that rule, I think many more monks would have
displayed it.
I have personally talked to such people [who develope such powers]
before and also heard from others about some others who have such
abilities.
Blue-mind if you start to realise the Buddhist truth you probably
would not be too bothered by these powers any more 
Venerable Pindola Bharadvaja is one of the Buddha's sixteen
disciples named in The Amitabha Sutra. Under the Buddha's auspices
he attained the holy fruit of Arhat. Once when in a jubilant mood,
he said to the faithful:
"Do you think flying in the sky is magical?
I will show you some spectacular acts."
He then jumped up into the sky, FLEW all around and performed many
miraculous acts. The faithful were all impressed and praised him
without ceasing. The Buddha was very displeased upon learning of
this incident. He asked the Venerable to come forth and admonished
him, "My teaching uses morality to change others and compassion to
save living beings. It does not use magic to impress and confuse
people. You have misused magic today. As punishment you to stay in
this world to work for more merits and to repent for this
misbehavior."
