In the technology world, so-called 'Easter eggs' are surprises that have been hidden in films and video games to be discovered by viewers and players. Electric car manufacturer Tesla has created some of its own Easter eggs for owners to discover in its Model S's infotainment system.

Below, we give a summary of the best ones.

Sketchpad

This Easter egg has been included in the latest v8.1 software update and turns the massive 17in touchscreen into a sketchpad. Once you've indulged in your artistic talents and are happy with your drawing, you're able to submit it to Tesla for judgement. Want to find out how to use it? Well, Tesla is keen to keep that under wraps for now - but if you think you can guess how then let us know in the comments below.

Trip to Mars

If you get bored of navigating around planet Earth, Tesla lets you turn Google Maps into the surface of Mars. Hold down the Tesla logo on the screen and wait until it pulses, then when it asks for an access code type in 'Mars' and you'll see the screen transports you to the Red Planet.

Psychedelic Cowbell Road

Have you ever felt as though your digital dashboard could do with a bit more colour? By activating the Autopilot function four times in quick succession, the colour of the road displayed on screen changes colour from grey to a bright rainbow, and a snippet of Blue Öyster Cult’s Don’t Fear the Reaper plays in the background.

Elon Musk claimed via Twitter that this mode is called ‘psychedelic cowbell road’, but it looks to us more like the colourful Rainbow Road circuit from the Mario Kart video game series.

Lotus Esprit Submarine

Elon Musk bought James Bond's actual Lotus Esprit submarine car in 2013, and it inspired a subtle Easter egg back in 2014 with the v5.9 software update.

Holding down the Tesla logo on the touchscreen for 8sec reveals the service access menu. Typing ‘007’ into the keyboard and heading to the vehicle controls menu will change the graphic of your Tesla into the Lotus Esprit submarine from The Spy Who Loved Me. Changing the ‘depth’ will instead adjust the ride height of the car.
