That was really disturbing and really amazing at the same time.   Disturbing in the fact that I really struggled to read the subtitles all the cool machines in the background may have distracted me.  But at the risk of sounding stupid are they really saying everything in the subtitles with there hands?  AMAZING. 
  I Had a step dad who was blind which was also amazing reading a book with brail I couldn't tell the difference between 1 dot and ten. 

  Really reminds us how good we have it.
