Arduino bluetooth wireless

Hy I'm pretty new to arduinos and i wonder if it's possible to connect two bluetooth arduinos together wirelessly and if not with bluetooth what other simple stuff is out there?

I've been working on the same thing recently.

The trick is the bluetooth devices have a "slave" and "master" mode. I would assume if you can put one into master mode and get the slave to register to it, you could do whatever you want from there.
