Each email gives a name, a workplace and a favourite fruit, and asks what we can make for them.

A few minutes later, an email comes back with a link to a website made just for them. On it is a smoothie recipe invented around their fruit and a character to go with it. One strawberry fan recently got Sunny the Strawberry Swirl, a pink and red swirl with a leafy green crown who gets about on a shiny red skateboard. Sunny stars in his own 15-second film, and the process also turns him into a 3D model you can spin around on the page. Further down, the site has slotted the order into the day's delivery run with a planned arrival time.

Behind all of that, the same process has added the recipe to a combined shopping list with estimated supplier prices and updated a live profit and loss for the whole imaginary business.

Nobody touched any of it in between.

It's deliberately a bit silly, and we wouldn't be the geeks we are if we hadn't printed a 3D Sunny to bring along as well. The idea behind it applies to almost any business.
