Surprise karaoke in a shop is probably one of the weirder things that can happen to you, but when the shop itself starts making the tunes, that's a whole new level of weird. Beer brand Red Stripe kitted out a corner shop in hipster central Dalston, London with hidden mechanics and props that started jumping about and making a familiar racket when someone picked up one of their beers from the fridge. It's a very impressive display, but what's more interesting is how they made it all happen (if you ignore all the brand hype shpeal they churn out). Can't see this happening in Spar now can you?
