As you've no doubt guessed by now, I'm a big nerd. Back to the Future is one of my favorite movies. Michael J Fox makes my eye twitch, but the characters and the story more than make up for it.
So, the fine fellows over at ThinkGeek have come up with a replica flux capacitor, the main component that makes Dr. Brown's De Lorean travel through time (1.21 jiggowatts!?) And it flashes! Ooh, soooo pretty.
Unfortunately, now that I've seen this, no driving experience will be at all satisfying until I have one of these installed.
