Plymouth progress widget

[Charlie Brej]

I am looking for ideas for the progress widget for the plymouth splash 
screen[1]. I have already tried having the sun being covered by an 
eclipse and showing a corona but that didn't look that good. The 
possibilities are unlimited and I am happy to code up any reasonable 
suggestions into prototypes. If you can supply a pixmap too then that 
would be useful.
