Our school is going to have a fund raiser so i wanted to add in something that would help raise more money. I was thinking of turning the computer lab into a lan party area. The problem is that there is no guarantee what the students might do when they rent the computers, so i want to restrict them to only playing the game, nothing else. I was inspired by this interface i saw in an internet cafe in which you either select the browser or a game and do nothing else. I would like to replicate this interface, is there any possible method, like a software i have to install or something like that? Can you kind people recommend me anything of the sort?
