Sorry about the lack of explanation for the code snippet in my previous 
reply...

#-- simple counter from 1 to 50
1.upto(50) {|index|

  #-- print the number of backspaces necessary to delete the number,
  #-- this is what causes the number to appear to refresh
  print("\b" * index.to_s().length << index.to_s())

  #-- pause 2/10's of a second before returning to top of loop
  sleep(0.2)
}
