Publicis Conseil launched its all-digital banking service, Hello Bank!, with a little help from B-Reel and 60 performers of the Czech National Symphony Orchestra. The video is an actual live performance of “March of the Toreadors” from “Carmen” conducted by Libor Pesek on April 30, 2013.

B-Reel created 227 interfaces for all 60 instruments in two weeks – all connected via wi-fi. The performance looks staged, so B-Reel also released a behind-the-scenes video for naysayers.

Here are some great screen captures from B-Reel of the mobile instruments.
