There's a couple of similar compounds but don't think it's been done quite like this before. The lightning forms the central vascular tissue of the leaf. Perhaps @Jens Windolf this is something of interest? Seems more of a natural union of the two forms.
While I created this idea independently and consider it the obvious next logical step for Jen's project - http://drbl.in/fdyA - this has been done before - http://goo.gl/6Cfon
