[LAU] [OT] SoundBeam alternative

Hi all, I'm using the soundbeam[1] for a project with music therapy and educational application; it's a great device with customisable sensitivity, it's possible to get midi messages from it, connect more than one, etc. On the other hand, it costs around 2000€. Is there anything out there that uses the same principle (a sonar beam to get your position) or works in the same way but which costs less? If open source, it would be even better. As always, thank you all! -- Marco [1] http://www.soundbeam.co.uk/
