It's shaping up to be a sweet week for patisserie lovers, with two hot new shops opening in London on Wednesday. First up is macaron magnate Pierre Hermé's first UK store, in Belgravia, filled with his mini-meringue delicacies – but if you want something with more heft, try Soho's Cox Cookies & Cake, set up by patissier Eric Lanlard and shoe designer Patrick Cox. The heft? The over-the-top Nanaimo bars: coconut, chocolate biscuit and custard vanilla buttercream, all coated in dark chocolate. pierre herme.com, coxcookiesand cake.com
Who's looking forward to the further adventures of Dave Lizewski? No? How about his alias, Kick-Ass? Mark Millar's comic-turned-box-office smash is back, in CLiNT, a new monthly magazine from the comic-book writer and Titan Magazines.

It might be a bit doom and gloom for some graduates, but not the five Central Saint Martins students whose shoes will be on sale at Bally from next month.

From dove-grey suede ankle boots to Plexiglas courts, the limited-edition styles are quirky, classy and set to become collector's items. bally.com
Where better to watch two new plays about our ecologically fraught future than in the UK's first theatre made from recycled and reclaimed materials? Built from wooden pallets and empty water-cooler bottles in a south-east London school playground, the pop-up Jellyfish Theatre will play host to these two productions: eco-disaster family drama Oikos; and Protozoa, a dystopian vision of a society on the brink of collapse. To 9 October, oikosproject.com.
Ever wondered what a light switch being turned on and off would sound like? Of course not. Thankfully, Turner Prize winner Martin Creed has more than one string to his bow. More specifically, he has a mix of post-punk minimalism to his bow, as he and his band will reveal at Wysing Arts Centre in Cambridgeshire on Saturday at the Be Glad for the Song Has No End festival of artists' music, which promises an experimental approach to making noise. And if you fancy making a noise yourself, pop along to Sonic Youth vocalist Kim Gordon's "reverse karaoke" yurt, where you play while she sings. wysingartscentre.org
