We're back with another instalment of The Spark, Creative Boom's bonus episode that gets under the skin of each week's guest. Host Katy Cowan is joined this time by Haraldur 'Halli' Thorleifsson – designer, entrepreneur, philanthropist and founder of Ramp Up Reykjavik.

In this playful after-show, Halli reflects on the first book that changed him, the moments he's felt out of his depth, and the creative hill he'd happily die on. He opens up about the small rituals that keep him going, the impulsive adventures that shaped him, and even lets slip who he'd invite to his dream dinner party.

It's thoughtful, funny and full of surprises – the perfect companion to his full conversation with Katy, released earlier this week.
