At 10:40 am, we hear Part 5 of Sydney By Design for this series and Ed talks about infrastructure.

At 11:00 am, I look at a great new exhibition and website at the State Library of New South Wales, called Botanical Inspirations. It examines the work of natural history illustrator Ferdinand Bauer, who was the illustrator who sailed with Mathew Flinders in the Investigator. He developed an unusual techniques of marking colours on his sketches by numbers and his palette comprised some 1000 numbers, which he had committed to memory. Professor David Mabberley cracked the colour code and has just  published a book called Painting By Numbers. This is also the name of the very inventive website that goes with the exhibition. My guests in the studio are curator, Alison Wishart and head of the DXLab which developed the website, Paula Bray.

Music features songs about infrastructure and songs about Australian flora and fauna.

I look forward to your company.
