Star Wars' impact on the world of film cannot be ignored, but George Lucas' iconic sci-fi series has also been a significant player in the world of tech since 1977.

From sound design to special FX, via computer games and CGI and from laser disc through to holograms, Star Wars has always been close to TechRadar's heart.

So, with May the 4th upon us, we've combed through our archives and put together an alternative list of Star Wars facts to fascinate and enthrall you like C3PO to an ewok.

We've got a good feeling about this.

1. Star Wars special effects guru Dennis Muren is backing a holographic version of Star Wars

Muren is often asked about the inevitable re-release of Star Wars on every single new format, but he told TechRadar that he was kinda okay with all of that adding: "If there is a way in the future to do a hologram version [of Star Wars] and the fans want it then it should be done.

2. Sebulba's pod racer uses the sound of a Ferrari, and Anakin plumped for a Porsche

The sound-design for Star Wars has been a source of fascination for years: most Star Wars fans could tell you that the lightsaber noise is a mixture of a TV cathode ray tube hum and film projector hum, for instance - but did you know that for the pod races nasty Sebulba was all Italian sports icon but Anakin's self-built offering was a bit more Bavarian hot rod?

3. It was seven long years before you could buy yourself Star Wars on VHS

In this modern day and age you can practically buy yourself a copy of the film before it hits the big screen, but there was a time when you had to be little more patient. The rental version of Star Wars was in 1982, but it was apparently a couple of years down the line before you could spend your hours rewinding the R2D2 Jawa bit until you could perfectly mimic the noise he makes when he s's hit by the stunner.

4. The Xbox 360 was redesigned as R2D2 to launch Kinect Star Wars

The game might have been a bit, well, Jar Jar, but when we're looking back at the greatest console designs of all time there might well be a place for this droidified bit of kit - we're not so convinced by the C3PO blingpad however.

5. Darth Vader selfie launched the official Instagram account

6. Six formats and a movie

By our reckoning, even without the remasterings and generally tinkerd with editions Star Wars has managed to get itself onto at least six different home entertainment formats: VHS, Betamax, Laser Disc, V2000, DVD and Blu-ray. 3D Blu-ray is yet to make an appearance - but we might just wait for Muren's Holographic version for now. Don't even get us started on streaming…
