I stumbled across these at http://www.dornob.com and seeing as we will be decorating our family home in the near future, something like this has now gone straight to the top of my "Oh my God, I must have that in my house" list. The original Pacman and Space Invaders, followed by life-size R2D2 home-help robot still top this list, but wallpaper games are now right up there. The difficulty will occur in trying to get this past my lovely wife, who although a constant support and inspirational figure - is also death to grrreat ideas. I'll try my hardest though.
