Update, Jan. 4: Sign-ups are underway now. PlayStation 4 players will need to supply their PSN ID, name and an email address, and agree to a private beta agreement. Sony said that signing up does not guarantee participation.

Dreams, Media Molecule’s make-anything-including-a-game-Media-Molecule-made-10-years-ago sandbox creator for PlayStation 4, is getting ready to open up a public beta as planned beginning next week. The studio is kicking things off with a livestream showcase tomorrow, which will be followed by the beginning of the sign-up period.

The Dreams Creator Beta started as a semi-closed test at the end of December, and originally exclusive to those who subscribed to the Media Molecule online mailing list. Back in December, Media Molecule said the plan was to open the Dreams beta to a wider audience beginning Jan. 8.

The livestream is at noon ET on Friday, Jan. 4, and will be available through Media Molecule’s Twitch and Facebook channels, as well as PlayStation Events.

The beta includes Dreams’ creators mode demo, which focuses solely on the creation aspects of the game. In a preview over the summer, Polygon also saw the Dream Surfing mode, which delivers users an endless stream of levels made by others from the community.

Media Molecule has been spooling out news about Dreams here and there since the ambitious toolkit was first announced in 2013. It’s due to launch sometime this year. For those who loved the LittleBigPlanet series the British studio created for PlayStation 3, Dreams is striving to give would-be games designers an even more detailed tableau to work with and more power and control over it. In fact, Media Molecule itself showed off a virtuoso recreation of LittleBigPlanet’s opening level within Dreams at the beginning of November.
