An idea...
When picturing Frankenstein, I think of all the Whacky
and Wild scientific gadjets involved. ..
Instead of just a Marquee art.. you could actually
insert Gauges (pressure, electrical, etc),
dials, Flip switches, etc.. into the
cab. Various lighted things.
(parts = surplus place or junkyard..ect)
You could add the occasional strobe flash to
act as lightning hehe Tho, that may be a
bit too distracting... could be limited in time,
as well as able to be turned off.
Same for built in Creepy sound effects.
I also like the Tesla posts.. which again, could be
created in 3d, using wood rings and pipes..etc.
THe actual name, could be cut out letters, that
hover in space (support wire behind) and
maybe are backlit.
