Are there any mirrored LEGO bricks? I recently built LEGO Creator 5770: Lighthouse Island which features a clever trick to build the lighthouse's lantern, using stickers on on a Slope Brick 2x2 and Slope Top 1x2x2/3:

Step 54 from Lighthouse Island Instruction Manual 1/3

It works reasonably well, but I'd like something better. Are there any official mirrored (or prismatic, but this seems even less likely) LEGO bricks?
