Hi All! First I want to apologize if I just broke some rule by posting the topic here. Before two years there was another biiig thread about that puzzle, but now I found it's closed. Anyway, about two weeks ago I broke the first step of the new puzzle and posted the solution here: http://science-bg.org/forum/viewtopic.php?t=4 The forum is in bulgarian, but there are enough pictures so you can get the idea. If someone wants more explainations, he/she'll have it :). I write here because if there is still someone interrested in solving this puzzle, this may be useful and time saving. Good luck and enjoy!
