Philosopher's stone

39 - Philosopher's Stone Puzzle
Inside this room you will see your first Philosopher's stone. There are many more in the game. They can move over the plates they are on. These plates need to be powered in order to move the stone, much like an electro magnet. When the plates are powered they emit blue or orange light. As a rule of thumbs, orange light means it can trigger something, blue light means it does nothing.
First thing you need to do is enable the ground plates. Put an item on the pressure plate at #43
Then move the stone east so you can get in the room to the north.
Now, stand north of the stone (so the grate is between you and the stone). Push the stone again (through the grate).
Now stand east of the stone and push it onto the orange plate (west). The door at #47 will open.
