If you have ever had to take a child to the pediatricians office then you know about Busy Beads. They are the colorful beads on a metal track that kids slide up and down and around and they provide kids hours of mindless entertainment.

What if you could take the concept of beads on a metal track and then fill your house with them. Okay, it's not beads, it's more like billiard balls but it takes up the whole house. I can only imagine the grief this man took from his wife for putting this up in the living room. I am sure his kids love it but to be honest after watching it a few hundred times I started to get a little bored with the idea.
