I was thinking of the same 3D structure you were thinking.  In fact, I 
have used a bundle of 10Ohm resistors in parallel wired to a bunch of 9V 
batteries in parallel to ignite a chemical fuse in a timed explosive.

90VDC shouldn't hurt you too bad, as long as your skin is dry when you 
tough the terminals.
