I'd like to let you know about CraftML, a new tool for making parametric models like this light sculpture you designed.
Inspired by your design, I used CraftML to create a similar stick:http://craftml.io/VyyBi

As you can see, my model is still an incomplete replication of yours; it has much fewer digits and follows a linear spiral.
3ders has an article about CraftML.
Hope you will find CraftML useful for making more amazing light sculptures!
