The Christmassy treats keep on flooding into CR Towers. Here are some more of the inventive ways that designers and ad agencies are promoting themselves this festive season... First up is illustrator James Majowski's take on Santa, which he calls 'On the origin of Christmas'.

We've all seen Elf Yourself, but now there's Delft Yourself, a uniquely Dutch take on the whole interactive Christmas card-film-website thing from 180 Amsterdam. Visitors to the site are encouraged to use their webcams to create their own personalised messages that will appear on the site in a Holland stylee.

Lean Mean Fighting Machine has tackled one of the great questions of the Christmas season with its website Snowman or Fatman? The site invites visitors to pick one option and then watch a small boy approach a snow-covered figure and kick it to reveal which is correct.

A more elegant festive message comes from Imaginary Forces, who has created a pretty film to celebrate the holidays. See it here.

New Future Graphic has created this cute film featuring a wrapping paper-machine. The paper patterns shown can then be downloaded for use on your very own gifts online here, and there are fun iPhone and iPad treats too.

Digital production house squint/opera has shown its dedication to the Christmas season by painting a giant Christmas tree across its office space.

Taxi Studio sent us in this rather lovely Christmas conundrum, in the form of an elegant wooden cube and a puzzle. We've yet to work it out, maybe you can solve it for us?

Publicis in London sent us this box of biscuits, which we were surprised to find were decorated with info on the agency's most successful campaigns of the year. Start Thinking Soldier (biscuit shown above), the Renault Mégane Experiment and Malibu were all featured on the biccies. Bizarre but tasty!

Finally, we end with a digital take on the exquisite corpse game by Big Spaceship in New York. Corpsify invites visitors to draw the head, torso or feet of a character, which is then joined to contributions by other users to create a unique figure.

CR wishes all our readers a very Merry Christmas. See you in 2011!
