The Fun Theory

How to make vacuum cleaning fun?
Everyone loves karaoke, SingStar and other fun singing games.
The Sing'n'Clean gadget for your vacuum cleaner is a game, where you can sing karaoke and score points while you are cleaning. The lyrics display is placed on the "head" of the vacuum cleaner, for you to read and sing them while focusing on cleaning.
A censor is registrating the ammount of dirt you collect and how well you clean the house. Points for cleaning and points for singing are added up, so you get a final Sing'n'Clean score.
You can compete with neighbours and friends in a worldranking on the internet. Submitted by Raketfabrikken
