Ok so I'm doing this thing with personal heroes redone as religious figures. In this case Tesla as Odin which fits with his background - talked to birds, saw things not there and sacrificed his life for what he saw as his life - his science - only to later regret it. He paid dearly for what he was and knew that he did so while he was doing it.

The symbol is a mix of the Odin symbol and Teslas engine, the tie since he is the god of the hanged/hanged god.
