Three things you won't want to miss in London this Friday

1. If we learned anything from 2017 it was that anything goes. So 'London Visions' at the Museum of London, an exhibition where artists, architects and designers dream up versions of London’s future, might seem fantastically wild but may well be eerily spot on. It opens today at 10am, entry is free. 

2. See new works by the pioneer of op art, Bridget Riley, as her latest show opens today at the David Zwirner gallery. Riley’s gorgeous shimmering paintings still have a powerful impact and they're free to gawp at. 

3. A Cadbury Creme Egg camp is popping up for five super-sweet weeks at 288 Old Street from today. Billing itself as a ‘secret woodland hideaway’, it'll feature a forest, a campfire kitchen and a tree house. Entry is £5 and you'll get a free eggy treat to guzzle down. Book your 5pm, 6pm, 7pm or 8pm slot online.
