Where can I find a certain spinning “aquarium” lamp?

My niece just changed her room to an ocean them and I really want to get her this lamp I remember seeing a long time ago to go with that theme. I think if memory serves correctly it was in the movie “Mermaids”.

Basically all it is a bright bulb beneath a rotating shade. The shade is covered in these translucent cut outs of fish. So when you turn all the lights in the room off and turn on the lamp, it looks like fish are swimming around your walls. Any help finding where I can get this lamp would be appreciated.
