Feels like there should be many ways to make a particular letter, and it'd be neat if it was random each time. I tried "Hello" and noticed the L's are the same. Considering it's just for fun I think it'd add a little more fun if it was actually unique letters.

Also, can we get a checkbox for "pause after animation"? I want to take a minute to check out the letters before it starts animating again. I know you can click off Animate after it finishes, but if I share this, others may not be so keen.
