Thank You, Hal for your comments. ; "But it ends very suddenly.." Also for me this is something to improve. Even Paul suggested to add some structure on an earlier comment. As of now there is an automatic algorithm that I start and stop but having some ideas. Will see and present the results when ready.. ; "How are you? My cats and I are still here.." I´ve been on a six weeks trip to my favorite spot and gathered some energy, ideas and flexibility. A few of the results you have seen. ; Cheers, Albrecht
