Here is an attempt at a Raspberry, using Flow.

1. Use SpherePoints script to make 60 points on a unit sphere.
2. CopyToPoints script to copy small sphere to the points, to create the object to Flow.
3. Create big unit sphere, to use as base surface for Flow.
4. Create an outline of a raspberry, and revolve, to make the target surface for Flow.
(Also revolved an egg for another target surface for Flow.)
5. Flow Rigid.
