Laptork is an Argentina-based laptop orchestra, directed by Esteban Insinger and Fabian Kesler.

The group uses laptops, along with custom software and sensors, to create a computer music orchestra:

We can see the relationship with the orchestra concept transfered to the present, where the computers are our sound generators (in a violin they are the strings), the sensors are the exciters (they are in a violin the arch and the fingers), and the speakers are the resonant bodies (in a wooden violin it is the box). Hence, we speak of an “orchestra”, because we keep its essence, its concept, but we think it from a modern point of view.
