Sony has released free console themes to celebrate the 20th anniversary of the PlayStation.
The free themes are available now - there's one for PS4, one for PS3 and one for Vita.
Each theme features a 'PlayStation 20th Anniversary' logo and is designed with the original PlayStation's colour scheme of a grey background and red, yellow, green and blue icons. The PS4 theme also plays the original PlayStation startup sound when you turn the system on, as seen in this Vine.
PSone launched in Japan on December 3, 1994 and immediately won over gamers, quickly outselling its rival, the Sega Saturn.
The system essentially turned Sony into Nintendo's new rival, setting Sega off on a downward trend that eventually led to its withdrawal from the hardware business.
It eventually came to the west in September 1995, accompanied by a unique marketing campaign that targeted a young adult demographic rather than children.
The introduction of games such as WipEout, Tekken and Ridge Racer helped Sony attract an audience that was beginning to feel as if it was 'growing out' of gaming.
A total of 102 million PSones were sold worldwide.
