Thanks, guys! Yeah, I made up the Christopher story for the installation, but I might like to do a children's book about it as well. For those who wanted to know more about the story, here's a (hopefully!) somewhat better summary:
Christopher is a young and mostly lonely (except for one childhood friend) prince, who is basically a normal kid, if a little naive. One day he and the childhood friend (the girl in the wallpaper, and one of the books that I'm not sure you can see in pictures) go out to their favorite spot to play and Christopher is attacked by the great snake Ezra who is waiting for him there. After a mighty struggle, Christopher defeats the snake, but takes up its stoic mask and wears it from then on so that any other monsters will be afraid to attack him in the future. The mask gives Christopher Ezra's deadly powers, but basically saps his personality so that he cares about nothing anymore.
When Christopher returns home, his overbearing mother, the Insect Queen, doesn't recognize her son and rejects him, instead obsessively collecting pictures and other representations of the son she now assumes is dead. His father, the king, is extremely paranoid, and sees his newly-powerful son as a tool to get rid of his enemies. Two such enemies are the Orthrus twins, Asher and Felix, who own an armory company and plan to assassinate the king. Christopher is sent by his father to kill the twins and return their hands (each with distinctive tattoos) as proof. The hand of Felix (the one with the wrist tattoo in the pictures) is put on display in a box, while Asher's fingers are each put into a box so that the king can send them to other enemies as a warning. Meanwhile, this whole time, Christopher's childhood friend, the only witness to Ezra's attack, still recognizes him and tries to pull him back to the way things used to be, but so far her efforts have been in vain.
There are a couple other things not really shown in the pictures (mostly the stuff in the cabinets; Christopher's childhood books and toys) but that's the main story. If you want to get all art-analytical, it's a story about children being placed in situations they aren't in control of or don't understand, and their ways of coping with those situations. Whew! Sorry that was so long!
Oh and as for what to do with the installation once it goes down, I give all the pieces to my friends and family, or, hell, anyone who wants to buy a chunk. I don't get attached to art very easily
