What might be a word for the shape with a lot of random projections and recesses? I would like to describe the shape of countries in Europe where countries have interlocking shapes like distorted jigsaw puzzles. Alternatively, what would be an analogy for irregular shape with female and male connections?
The analogies which come to my mind are:
- irregular jigsaw puzzle
- inkblot, puddle, blood pool
- amoeba with its tentacles (pseudopods)
