First off, a comic book about Tesla and his (best?) friend Mark Twain. No, seriously, they were friends in real life. How cool is that? It's called the Five Fists Of Science--again, how cool?! If you want kids to be interested in science, this comic book would probably do it, although if I remember correctly it's a little science fictiony, although no more than The Prestige (which is also awesome). Okay, maybe a little more fictiony than that.
Next up, these really swanky posters from Meganlee over on Etsy.
Tesla here is part of a set of scientists, and if they dark color isn't doing it for you, here's a really bright version.tend to have that problem.
Next, check out these amazing lamps from VictorianMachines on Etsy.
Anyway, if you have never read about Tesla's works, you really should read up on him. He was working on a death ray! Like, a seriously bona fide evil scientist death ray. And he thought Einstein's theories were bunk. And the ladies loved him! Although I don't think he returned their feelings. Bros before hos, right Tesla? I can only imagine that if he were alive today we would definitely have space travel by now. And death rays.
(oh, and Edison is such a jerk)
