Check out the latest video I made using the latest WIP of RetroCopy. You way want to watch it in 720p for full effect. 
The "space effect" is something I think looks better than the previous background. However I'm thinking of letting it be customized so you could add say a zooming Sonic mixed with some game art. You can't see it in the video so much but moving the mouse also somewhat affects the background, whether rotation or the speed of the zoom.
Something you can see in the video is the ability to make the bottom half of the screen (ie game covers) take up the whole screen. Which makes viewing the covers a bit nicer. I actually got a LOT of coding done today so hopefully we are not too far away from a beta.
