What about a sideline associated product ?

When I used an example of a tropical fish tank I noticed the applications could be extended to other practical purposes apart from merely improving your computer. My gf suggested using an old lap top behind an old fish tank to give the illusion of a real tropical fish tank that would cost thousands in purchase and upkeep maintenence This is only a rough example, but I am sure that the manufacturers might improve the idea but the company could make some exra money out of this. The application could be used commercially too in hospital waiting rooms for instance.
