Thr3fold challenge

When I was reading the new Thr3fold magazine the challenge sounded very tempting to me. I have been going over the idea a number of times and I am going to do it. Don't know yet whether somebody else will join me with this challenge, but I am going to start anyway. As inspiration source I will focus on the big pond which is in front of my house. There are 5 little islands in it and at the moment a family of swans (mom, dad and 4 young ones).
