custom plymouth theme

[Chris Cole]

Hello all, I would like to make a custom plymouth theme for Ubuntu 
10.04. I followed the instructions here:

http://www.ubunturoot.com/2010/05/how-to-create-simple-plymouth-theme.html

But it falls back to the default Ubuntu splash. I haven't been able to 
find anything that works.
Do you all have a guide that can be followed?

Thanks,
   Chris
