      Hi all,

      Hoping to create a particle system or systems which will create the effect of the fibbonaci spiral.

      Bit of gravity and velosity trickery is required but I'm struggling to work out how to achieve it's spiral shape.

      Anyone have any advice?

      Many thanks

        You can achieve this using the Javascript actor in Isadora Version 2.
        This link provides sample code that can help you along:

        Depending on the coordinate system used in the code (likely 0,0 as bottom left or top left)  you will need to offset those as well to get the data to map correctly to Isadoras center 0,0 coordinate system.

          Our department will be without isadora 2.0 for some time unfortunately.
          However I've created an effective spiral by simply rotating the emition point.

          Cheers for your advise though, I can't wait to get my hands on the new version.
