Hold onto your butts, aspiring hackers, because you can now relive the thrill of breaking into the Jurassic Park computer system.
Jurassic Systems is a recreation of that computer system, based on the scene in which Ray Arnold (Samuel L. Jackson) tries to bypass the obnoxious personal coding touches of Dennis Nedry (Wayne Knight).

The simulator, created by Tully Robinson, has a couple working features designed in the IRIX style and sounds like a clunky '90s computer.
You can engage with several working command lines in the simulator, activated by typing "help." To activate Nedry's annoying system lockdown, make three attempts at unlocking the security system. Try typing "access security," "access security grid" or "access main security grid."
You'll be greeted by the familiar Elvis-bodied Nedry taunting you for your lack of manners, just like in the movie.

Type "is" and then ask to display the program's response for a surprise reference from the film.

Jurassic Systems may indeed be a tribute to prehistoric technology, but we must admit, the 404 error page would still hold up on any site today.
