Enigmistic?
and where are the spirals? :
I told at the begin topic, those spirals at on my garage at a residence at Brasov in Romania.
I filmed those pictures with my mobile phone.
If you want to come here at me to looking and studying those spirals, I can say the adress. But unfortunethly, those spirals maybe erased, by snow. Now at me is winter. At springs if those spirals was erased, maybe will appear new spirals.
Those pictures anyhow are keeping here on FRACTALFORUMS.
