"Technology Tickets". Each Sunday give the kids 10 tickets. Each ticket = 30 minutes of t.v., game system, computer, etc. Tickets can be used consecutively, but when they are out they are out for the week. Parents still reserve the right to say "no" even if they have a ticket. - cool idea, but I think I'm too in love with movies & tv to do this one .. maybe for things like video games or something..
