"Did you open it the associated rhino file as well?  Also, it uses Hoopsnake to iterate using the rule, so you need hoopsnake to run it.   With that definition I was just trying to interpret the relationships between geometry in rhino as a…"

"How do you think you would start adding more rules to this? I've been looking into this also and am fascinated by it. I am just struggling as to how to input rules to these scripts, all the examples i've seen leave that out…"

"I know this topic is quite old now, but having just finished the school year, I decided to take another stab at figuring it out.  At the moment I'm exploring the possibility of using the transform components to map the rules into a script.…"

"SWAP put out a shape grammar plugin for Rhino 5 called Grape-Shape. It is still in Beta mode (written in C#), however, seeing a grasshopper plugin/script like that would be an interesting proposal indeed. http://plus.swap-zt.com/2010/09/grape-1-0/"

"Sorry, it's been a while since I worked on this project. My approach was to code small C#/VB blocks to solve the formal manipulations. Although I'm still very interested in shape grammars and their implementation in Grasshopper, my project…"

"Hey Javier, Did you get anywhere with this? I am also interested in implementing a shape grammar interpreter in grasshopper. Does it have to be coded in a scripting component, or is there a way perhaps to reference the rules with shapes in rhino…"

"In case anyone's interested, here's my work so far. It seems to work, but it still doesn't account for an outer border and it ends up with more triangles than i'd like. Just scroll through the generations. I'd appreciate any…"

"Here's a guess at an algorithm: extract the "road" curve. Rebuild it to create straighter segments Reposition all the nodes of the voronoi diagram so that they are the same distance from the "road"."

"Yeah, this has intruiged me too after Ludger Hovestadt showed a glimpse during his lecture at our school. I wasn't able to come up with a satisfying algorithm, so I'm repeating your question: Anyone?"
