Plans or Ideas Wanted or Needed

[Jack]

I am looking for the plans or some suggestions on how to make a ball in a cage. I know that I have seen it somewhere but I can't seem to find anything on it at the moment. If I remember correctly it was about 4" long and about 2" on the other two sides and all that is left is the four corner pieces with a ball inside that can roll back and forth but not come out. I have seen them carved out of wood with a carved chain attached but what I'm looking for is made out of Aluminum. Can anybody help me.

Thanks
That's not exactly the one that I remember but its good enough for the girls that I go with. I'm sure it will be a challenge to make and definitely a machining exercise.
