As a holiday fundraiser for Save the Children, San Francisco-based digital marketing agency Carat Fusion has come up with an interesting – and calorie-free – concept: virtual cookie-making. For each gingerbread cookie visitors to its website design and bake online, Carat will contribute $1 to the kids’ charity.

Participants in the cookie party can get artsy with virtual icing or personalize their cookie masterpieces by uploading their own photos. The results can then be viewed on Carat’s holiday cookie gallery, or passed along to friends. Until Dec. 22, all are invited to design and bake these very special cookies at: www.caratfusion.com/holiday2006.
