Need cool suggestions for a Fretless jazz bass paint job

So, I'm gonna convert my SX jazz bass to a fretless and i want to repaint it.I don't want it to be just like Jaco's bass of doom and I also would not like it to be to dark (because my Warwick Streamer is already dark brown).Any cool/crazy suggestion is welcome.Thank you!
 
I've always wanted to do something like this!
