This beautiful piece was made for a canadian client, a design firm. The piece connected to the computer captures and delivers the signal from the chest strap. The usual cardic monitor only reads the signal, with this USB device it can be monitored and stored.
The illustration is based on placed art, with a controlled redrawing. It works like an infographic, but there is no need for text boxes.
The client was contacted trough Craigslist. He paid right when arranged. A rare ocurrence these days.
