I have been offered a studio in Cloud Party for a few weeks. The aim is to develop public art. I think this could move on from Twinity. Cloud Party works in a browser, there is no need for a download. However I don't think you can have a screen or radio with a feed from another website. Maybe this will come later. This is still an early stage for Cloud Party. Once you have several video clips or bits of sound then a virtual studio ought to help to link it all together. You can either record something or let the public make their own choices. There is a phone in Cloud Party that takes stills. I don't think there is video yet.
