Cellular Like OpenSCAD Bracelet

I really like the bracelets user nervoussystem creates, but only their finished designs are available. This is a quick approximation in OpenSCAD.

It's inspired by, but not a derivative http://www.thingiverse.com/thing:7047

This design is fully parametric so you can define the diameter of the circle, the number of holes per row and the number of rows that will get stacked up to make the bracelet.
