Anyone tried hackadays "lightblue-bean" ? ( arduino+accelerometer+bluetooth..)

i just stumbled across this thing and thought it might be an easy way to build a simple headtracker - anyone has some expirience with those ?

I built my own Pro Micro+GY-85+HC-05 BT for less than that. It doesn't really work reliably yet as the firmware needs some work, so I'd suggest you look at something supported like Edtracker. They use a Pro Micro+MPU-9150 but no BT, although apparently they're working on a RF wireless version with a custom receiver dongle.
