CPU sign in Openscad (OV chipkaart)

thingiverse

This Dutch design is used for electronic payment in buses, trams and trains (http://www.mediamatic.net/page/155204/en). The sign indicates credit deposit or withdrawal from a chipcard. Though visually appealing, repetition may cause monotony. To enhance it, I utilized the polygon generator program (thingiverse.com/thing:9290) and integrated the design into an Openscad document by using "#cpu sign.scad#" or directly opening "cpu sign.scad".
