Bananasioug, I agree with your statement that creativity being replaced with code. Congrats on this very creative entry, and good luck at the judging!

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!
