Can someone identify this rock?

I found an interesting "rock" the other day. I originally thought it might
be a meteorite because of the spherical structures within the rock. As you
will see if you click on the links below, this "rock" seems to be broken off
from a larger piece. There exists many spherical structures.

Any input would be greatly appreciated.

Thanks,

Ken
