As mine and Sam’s project involves connecting Arduino and Flash, I figure other software connections might be helpful to some. My group used this Geco add-on for grasshopper to link it with Ecotect for formal analysis. There are quite a few free component add-ons for those grasshopper kids out there and this one is pretty neat.
The grasshopper forums also have quite an extensive amount of help and tutorials for those still learning. Check it ouuut.
