Only a suggestion, how about a blue-ish hue to on the Katana's blade as 
the boot progresses to give a sort of feedback? (instead of a progress 
bar as such, using the same logic that would apply to a progress bar), 
though I'm not sure how feasible it might be, especially considering 
graphics overlapping, added overhead, code involved, etc.
