Christmas is the most wonderful time of year, but it can be tough. You want to make your loved ones happy, but you also want that amazing shiny new thing for yourself.

Three hit on the insight that self-indulgence is big at Christmas, but that it doesn't stop people wanting to treat their loved ones. And that’s where Three's generous Christmas promotion comes in: splash out on a gift for yourself and they’ll give you a discount on a gift for someone special. 

It's the best of both worlds: treat your loved ones at Christmas, by treating yourself at the same time.

To help Three sing the news from the (metaphorically, unfortunately) snow-dusted rooftops, we conceived a campaign that really makes Christmas all about you, via a specially designed app called CalendarMe. If you ever dreamed of having your own celebrity calendar, thanks to Three, now you can. Because what could be a better gift for your fans, er, we mean loved ones, than giving them 365 days of you?

The app, created with the technical wizardry of Unit9, uses clever colour-matched image replacement technology to insert users’ faces into their very own calendar. All you need to do is visit www.three.co.uk/CalendarMe, take a snap with your webcam or upload a photo, and Bob’s your Christmas-jumper-wearing uncle, you’ve got your mug on a digital, downlaodable and infinitely shareable calendar. The lucky recipients will be treated to a whole year of you: you as a mechanic, you as an astronaut, you as a long-haired member of a metal band, and more. Aren't you thoughtful?

While you’re assembling your one-of-a-kind calendar, our charismatic and flamboyant host Marcel will be there to guide you every step of the way and give you little bursts of ego-boosting encouragement.

Look out for something fun while you're out tackling your Christmas shopping too, with interactive posters appearing in select shopping centres, which allow you to play with the app right there. In the press, additional executions let you take a rather more analogue approach with a simple cut-out mechanic. 

This Christmas give them what they really want. 365 days of you. Have a go at making your own calendar, and who knows, you could be one of the lucky 10,000 people finding a little calendar-shaped present from Three in their letterbox. 

Merry Christmas me…and you.
