George Monbiot wants to turn the global food industry on its head – from radical changes in farming practices to 3D-printed steaks. The prolific writer, environmental activist, and rewilder, explores this and more in his latest book, Regenesis.

Then it's time to meet an eccentric, little-known modernist architect who fought conventions and eschewed publicity: Bill Lucas. His friends and colleagues Peter Longeran and Julie Cracknell join Blueprint to find his traces in Australian architectural history.

And then it's time for a little bit of magic. Colin Bisset gives us the design history of the magician's wand.
