Put fun things like wooden chew toys, paper towl cores, small plasic balls (large enough that piggie can't fit it in their mounths), toys with a treat in the middle, and other things for them to climb on. Switch the toys around once every week or so to keep the cage intresting. You shouldn't rearrange the cage too much or you might confuse you pig.
Also, try putting something with a bell or rattle in it. My two babies love those kinds of toys!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
