Code is cheaper, infinitely copyable (with little to no cost per copy), and generally you end up with reduced part count. I also take issue with a statement that implies coding is not creative. I strongly beg to differ...

BTW - your project is still a pretty cool application of 555s - I hope you do well!

:)
