Getting spheres to collide/vibrate in Kangaroo

Hi,

I am trying to create an installation that moves depending on wind conditions.

I have created this vaulted form that supposedly undergoes a wind simulation (controlled by an MD slider). The pink spheres, represented as helium balloons are extended out from lines (from points/particles of the kangaroo engine). Currently, the balloons merge together when they come too close. Is there any way that I can make the balloons repel upon contact with other balloons and the mesh? Would be great if they can vibrate as well...

Yeah. Use the Collide Spheres force component in Kangaroo.

By vibrate, what do you mean? Like the whole structure? Individual balloons akin to atoms? Or just oscillations in the wind?

I have already achieve a swaying motion of the entire structure by using wind force. Would be great if I can get individual balloons to vibrate and slightly bounce off one another/the mesh.

Not actually sure how to use the collide spheres force component in Kangaroo properly.

just assign all the centers of the balloons to the first input and their radii as the second.
