Hi Simon,  Nice to see all these images you are showing us. At the moment you appear to be almost the only one doing so, so thank you. Along with others I'm sure, my excuse is being quite busy with other things, but I'm still finding that I need a lot of time to process my data, so what time I have doesn't get much done.   That saying that you can't teach an old dog new tricks is not entirely accurate, they (me) can be taught, but they need to be re-taught every few days for a while afterwards.   There are lots of intriguing creature like things in there and it has me wondering why they don't all just end up as regular shapes. Might be a boring scene if they were I guess.  Hope all is well at home and thanks again for sharing these great photos.  Best wishes,  Ray
