%N A106694 Fractal-jump sequence (FJS) based on Pi.
%e A106694 Start on the first digit (3), underline it and jump over the next 3 digits; 
               you land on (1) which you underline and leave by jumping over 1 digit; 
               you land on (4) which you underline and leave by jumping over the 
               next 4 digits; you land on (1) which you underline and leave by jumping 
               jump over 1 digit; you land on (5) etc. The underlined digits show 
               the decimal expansion of Pi. If you now erase all those underlined 
               digits the resulting sequence is the one you started with. [To jump 
               over "0" digit means moving to the next digit on the right, of course]
