Brett Foster made a working 1:12 scale television for his daughter's dollhouse -- you can hook it up to any traditional TV peripheral, like cable feeds, consoles, DVD players, etc. He's selling them for £99 (US$6,700,232.22).

"The TV's are easy to install, they have a very clear crisp picture and are a must for any dolls house enthusiast," added Brett.
"With the colour TV being common place in homes from the 70's and 80's it stands to reason that they would find there way to the dolls house scene."
