Steampunk tangible interface for music

Being a great fan of all the electro-dub production of french label Jarring Effect, my interest has been drawn by a device designed for Ez3kiel's last show, created in partnership with Medias-Cités. That blogpost by Clement Thierry has a good write-up (in french though) about it.

Called "cycloharpe" (bike-harp), this installation is meant to allow the user to change the music titles of the band's new album. Pedaling and using old-school buttons on this Jules Vernes-like device allow to control samples through different melodies and rhythms.

Why do I blog this? just found curious this steampunk tangible interface to control sound.
