And now, for something a bit different: Lenka Clayton and Michael Crowe are two creative artists with a very special goal - to send a personal handwritten letter to everyone in the world! Impossible? Most likely. Crazy? Perhaps. But it's surely different, and they are doing their best to do it in a creative and mysterious way - they call it Mysterious Letters.

In April last year, they have sent handwritten letters to all 467 households in the Irish village of Cushendall - not bad for a start. And in November, they wrote 620 letters - all different and personal - to each home in Polish Hill (Pittsburgh, USA). Here's what BBC had to say about it:

But they are not stopping here. Now they want to go even bigger and write to even more people!

This time, they are allowing anyone to get involved in their enthusiastic plan - they have setup their project at kickstarter.com so that people can donate towards it (if there aren't enough supporters, the donation is returned).

In exchange for the donations, they are offering peculiar things - from allowing the supporters to choose a theme for the letters they will send, to actually receive handwritten letters from Michael and Lenka themselves. For the largest supporter level, they are even offering to hand deliver a letter to the supporter in person!

Even though it sounds a bit crazy, we love the creative way they are doing it all. You can find more information about the project at their Mysterious Letters blog and for details of how help them, check here.
