Eclectro Last.fm Lovewall (interactive bluetooth installation) from Wilbert Baan on Vimeo.

The Eclectro Last.fm lovewall is an interactive installation that uses bluetooth to scan for mobile phones. Visitors are asked to change the bluetooth name of their phone into their Last.fm username.

A laptop scans the room using the open source Roomware software. It connects to random visitors and searches the Last.fm database for similarity. It then shows the similarity on a big screen by showing the profiles. A percentage and five artists both have in common.
