Things to do
IMAGINARY CITIES: New display Imaginary Cities opens today, looking at how new digital technology could change the way museums store and display their collections in future. Works by artist in residence Michael Takeo Magrude combine traditional materials such as historic urban maps with cutting-edge digital technologies to create fictional cityscapes for the Information Age. British Library, free, just turn up, 5 April-14 July
BEASTS OF LONDON: One of the most-hyped exhibitions of the year, Beasts of London opens at Museum of London today. Less traditional exhibition, more digital immersive experience, it tells the city's history through its animal residents, all of whom are voiced by celebrities. Read our full review. Museum of London, from £8 adult/£4 child, book ahead, 5 April 2019-5 January 2020

LAST BREATH: Watch newly-released documentary Last Breath, the true life-or-death story of diver Chris Lemons who got trapped 300ft down in the North Sea while diving to an oil well. A storm caused loss of power to the ship that Lemons and his diving partner were tethered to, a story told here through interviews, reconstruction and real-life footage. Screening followed by a Q&A with directors Alex Parkinson and Richard da Costa. Bertha DocHouse (Bloomsbury), £12/£10, book ahead, 6.30pm

ANTARCTIC EXPLORATION: Antarctica may seem like a mystery compared to other parts of the planet, but there's plenty to be learned from the continent.

Royal Institution (Mayfair), £16/£10/£7, book ahead, 7pm-8.30pm

ALGORAVE: Raves and libraries don't usually go together, but things get techno at British Library's algorave, which brings algorithms to life using music and visuals. There's a bar open all evening, and plenty of demonstrations and things to see alongside the rave itself. British Library, £15/£10, book ahead, 7.30pm-11pm
