Anyone know what this is?

As the title. Can anyone identify this plant? All that I know about it is that it grows on trees...

 

That's interesting Sandy

Just did a google image search, turned up this

 

Looks like a Tillandsia of sorts

 

@Sirius, after reading a little on wiki, I think that you are correct. Fascinating plant.

Edit: That was a fast reply!

 

Definitely a flower.

 

Kind of thing you often see in garden centres sold as "air plants" bromeliads that grow as epiphytes.
