Just starting messing with Dreamscene for Vista, (basically putting a video as a background rather than a picture) and it's quite interesting. Would recommend people give it a go. I'm looking for some good content for it though, most of the videos that I've found for it are either too short so looping looks awful or the camera constantly moves so it ruins the effect.
I'm looking for some good fishtank videos to start me off, I've found a few but can't seem to figure out how to save the preview? Don't really want to buy a fishtank video!!!
