Hmm, I get the following:

  [scotty@Scotty-Allens-MacBook-Air ~/bin]$ spark 1,2,3,4,5
  ▇\c
  ▇\c
  ▇\c
  ▇\c
  ▇\c

I suspect this has something to do with my terminal settings, but I'm not sure quite what...

Nifty idea, regardless.

add a '-e' after 'echo' on line 120

Try changing line 120 to

  echo -e $"$(print_tick $number)\c"

And it should work fine.

I found it necessary to escape the backslash

         echo -e $"$(print_tick $number)\\c"

The "\c" escape sequence makes the -n unnecessary (as I discovered while reading "help echo").

(in addition to line 120, there are some "\n"s in the help)
