Good day! My name is Irina. I and my 2 team mates(Alex and Tudor) are students at DIA - Mastercourse (Dessau, Anhalt, Germany). This semester we are working on developing the masterplan for the 2012 Olympics in London. We've made several pattern studies and urban analysis and in the process we have used also the magnetic field definition for grasshopper.
To make a general idea of what we are working on you can visit also our blog: http://diastudioxss09.blogspot.com/ Right now i am writing you because we are a little bit stuck and we thought that you might be able to help us. We are trying to use the magnetic field lines in our design but we weren't able to make grasshopper draw them for us. Do you think you could help us with that? Or at least give us some good advice we could follow in order to make it happen? Thanks alot! Hope to hear good news any time soon now! All the best!
