I found two bugs in the behaviour of the items rendered inside of the glass bell:

1: the Items diappear when you reenter the world, but they are still in the inventory of the bell.

2: the items double their turning speed, when you add a secon bell with an item.
I think there is a global rotation variable, that gives the items the rotation, but every itementity updates it again in one render cycle.

Hope my english is readable :)

Don't worry, it's readable :)
But the Glass Bell is very WIP. pahimar's still sorting out all the bugs :P

Fixes the item spinning thing, and makes the items inside look prettier.

Still have to get it synching up when the player approaches them though. Getting there :)
