Who are they? http://www.bubblejoy.com/ is based in Sausalito, CA and founded by Kevin Sherman in 2007. KShermanStudios is a privately owned design and development group that develops unique advertising, e-learning, and viral games for first-person video interaction as well as creating self-publishing video services.
About the product: This service enables anyone with a webcam to create quick and fun interactive video greeting cards for their family, friends, and now includes a direct tie-in for Twitter members as well. It basically looks like a talking image postcard and the tweets look and ‘pop’ like a bubble, hence the name – bubble of joy.
More details: These bubbles are free to tweet and send as a greeting card, you can choose your layout/skin, and are fun to make!
