Yeah, as I posted above, the whole design was inspired by the megaman splatter T-shirt - so I always intended on using splatter (although I figured out the specifics as I went along).
You're completely right - I designed the control panel without splatter and the empty space needed to be filled by SOMETHING. Given that I have the overall splatter theme... I went with that.
Combining the feedback (even the "jizz" comments
) - I've reduced the splatter and used a sunburst to fill the empty area. It's not final, but I think it's looking better.
