Skin System

Isaw this skin on one of these projects I have linked:

http://www.evolo.us/competition/rhizome-tower-a-thousand-undergroun...

and I'm assuming this was probably done on grasshopper, however I haven't seen any grasshopper videos or tutorials that would somehow emulate what's going on with that skin, other than maybe with attractors I guess?  Is it done by applying a picture to a surface, and subdividing it? Anyone know an example of how this might be done?

Thanks...
