The "St. Jude Dream Adventures" campaign, the 360-degree virtual experience room at the Memphis, Tennessee, location, lets children too sick to leave the hospital experience what it's like to travel the world.

Here's how it works: An Expedia employee will travel to the child's dream location, which can be anywhere from an underwater tour to watching wild horses in Argentina.

Once there, children will have the experience in real time with the employee, which gives kids the opportunity to ask questions and learn from tour guides.

The project is the brainchild of the 180LA creative agency. While this initial exhibition only featured four children, the agency said it's talking with the hospital about making it a permanent installation.

180LA, St. Jude and Expedia have teamed up before. A few years ago, the trio released an ad where Santa flew coach around the world so he could donate his Expedia+ points to the hospital.
