If you love Jurassic Park (and who doesn't) you'll find this to be pretty cool. Tully Robinson created a web page replica (jurassicsystems.com) of the operating system Dennis Nedry (played by Wayne Knight) has locked down, driving Sam Jackson up the wall in one of the more memorable scenes from Jurassic Park.
The actual password was never revealed in the film, which makes this "game" that much more fun. And if you type in enough wrong passwords, you get the infamous Dennis Nedry icon saying "Ah ah ah, you didn't say the magic word. Ah ah ah, you didn't say the magic word."
So hold onto your butts and see if you can break Dennis Nedry's system at Jurassicsystems.com. Also take note that the site mentions there's a hidden feature on the page somewhere. If you figure it out, please let us know!
