If you have installed from git, then there is an example theme (called script) 
installed, which does a simple throbber.
Take a look at /usr/share/plymouth/themes/script/script.script

I wrote a very rough guide to most of the elements involved in the language here:

There are two more examples I played around with if you want to see some examples:

You could edit the code and add a theme setting to choose between roundrobin or 
backforth.
Or use the script plugin to make a new theme. There was a spinfinity scripted 
plugin already made but I removed it from git:
