as promised here's a little DIY project. I hope you'll find it helpful. I have said it in the pics but I'll say it again. Most of this was not my idea. I have just come up with a different design and a little hopefully helpful gimmick...
I have also posted it on the forum I use in germany and people have already confirmed that very similar attempts have been made to engineer motiondecoys. The next season will show how the Motiondecoys hold up.
Maybe that's the format your iPhone views image but not the way a computer or forum reads them I'm not sure why seeing I'm not any kind of computer person
