Did you ever want to get the feeling of flying through clouds and stars while actually flying through clouds and stars?

Boeing Corp. is trying to make that come true.

In a wild and innovative take on cabin mood lighting, the airplane manufacturer has applied for a patent to project images of clouds, stars, blue skies and more onto the interior of its cabins, according to Quartz.

The patent request was filed last week.

It would allow Boeing to be the only jet that can project images onto a jet’s interior surfaces. The projections would occur in real time, allowing passengers to be lulled into thinking they actually were moving through clouds and, at night, stars.

“Projection lighting is simply one of many technologies we are exploring to see if it can bring advances in both airline economics and passenger experience,” a Boeing spokesman told Quartz. “In theory, airlines could use lighting enhancements on the walls and bulkheads to display information about destinations or to project scenes that get passengers thinking about where they’re going.”

Such technology is not new. Here is a video from 2014 talking about exactly the same idea when the concept of windowless planes was first announced.

“These ceiling projections could be scenes found in nature or helpful information for passengers projected on the walls and bulkheads,” Mike Sinnett, a VP of product development at Boeing, told CNTraveler last year when the idea was first announced. “Airlines could use these lighting enhancements on the walls and bulkheads to display information about the destination or to project scenes that get passengers thinking about where they’re going."

Here is Boeing’s video of what such a system might look like.
