What Kind of Information is Hidden in Barcodes?

Posted to Data Art  |  Nathan Yau

Barcodes. We all know what they look like. They’re the black stripes that vary in thickness with numbers that indicate something or another, but what is that something? Every product has a unique barcode number and when you pass it through an international key database, you get information about the product and the country of origin. Daniel Becker uses this data to create art in Barcode Plantage.

Once a bar code is keyed or scanned in, the program sends a request to the database, which returns a master file data. This master file data is then analysed to define positions, curves and colours of Bezier curves of the tree structure.

The number of these curves will vary correspondence to the number of figures in the code. Simultaneously, the user will hear a melody, which is based on the figures of the bar code.

Because every barcode is unique so is the resulting tree. Pretty.
