I am new to Grasshopper and Rhino so it may be an obvious problem here.... I am trying to set up a series of columns that expand and contract given a certain angle.  I am hoping that i might get this angle to react to an attractor such as a sun path .. so far i have tried with just a single point as an attractor but i think i may have not defined the vectors properly.  If anyone could help it would be greatly appreciated.
