FireMonkey Transparent Theme

I saw in a post that FireMonkey has a theme for transparent LCD screens (http://www.youtube.com/watch?v=pVCeduZRMkc). The theme looks impressive and like something out of the film Tron, however I don't know how well it will work with transparent screens, the controls are the standard set which I don't think will work that well on touch screens. I think for touch screens there needs to be a set of new controls developed.
