String to fold: 

XOXOOOOOXXXXOOOOXOOXXOOXOOXXOOOXXOOOOOXX

Random fold (* means dead end, backing up):
  X                 
  ↑                 
  X←O               
    ↑               
    O←O X←X X→O→O→O 
      ↑ ↓ ↑ ↑ ↓   ↓ 
      O←O O O←X O←O 
          ↑     ↓   
      X→O→O   X←X   
      ↑       ↓     
O→O O→X     X←X     
↑ ↓ ↑       ↓       
X X→O O←O←O←O       
↑     ↓
