As far as I know, and anyone can feel free to correct me I'm in error, I have made a custom screen for visualizations in my install so this may work. Copy over the element from the player screen that has the visualizations. It should be an "A01" line in the skin file. Paste that into your menu.skin file, and resize as appropriate. Inorder to get the visualizations to start automatically, run the "VISU" command on startup.
I think that would work for you. Maybe, maybe not. Trial and error is part of the hobby i guess.
