• Passengers will have virtual reality "windows" to view whatever they want
• Rotatable engines will allow the Sky Whale to take off vertically
• Viñals designed the aircraft to have self-repairing wings

(CNN) -- Give a designer and aviation geek some time and a pencil, and you might just get something great.

At the very least you'll get something spectacular.

Oscar Viñals, a Spanish designer and aviation enthusiast, has released details, and incredible pictures, of what he is calling the "greenest aircraft imaginable."

Inside the world's strangest-looking airplane

Equipped with self-repairing wings, large windows, a vertical takeoff ability and room for 755 passengers, the "AWWA Sky Whale" joins several other outlandish proposals for future aircraft that have cropped up in the last couple of years.

Airbus predicted we'd be flying in transparent planes by 2050, while pilotless planes and space flight have also been forecast .

Viñals' design uses hybrid engine technology and "active wings," among other things, to create a plane that, should it ever get built, will not only look great but will be one of the safest and most efficient planes in the sky.

The gallery above describes some of the features.
