The Art of London - Today's Happiness Experiment entry

A talk by gifted and original photographer/artist Emily Allchurch at Channel4, followed by a lovely chance encounter with her later at Frost & Reed gallery in St James's where her current exhibition Urban Chiaroscuro is hanging. She's clearly a great lover of London.

An autumnal afternoon walk through St James's Park with artist Laura Williams, creator of Aluna, the lunar clock - a hugely ambitious public artwork destined to appear on the north bank of the Thames opposite the Millennium Dome at the site of the East India docks. Another lover of London.

Watching the Marx Bros in Duck Soup with the Enfants Terribles - D schticking himself - especially the mirror scene

Bonus pleasures:
Finding out, out of the blue, that Big Art Mob has been shortlisted for a BIMA Award in the Art & Culture category

A splurge at Hatchards bookshop in Piccadilly including Peter Ackroyd's new book about the Thames, Robert Harris' new thriller, the first Biggles book for N, Michael Ondaatje's new novel for U, and a John Updike for book group
