Wow! There is a Gangnam style christmas tree.

This christmas tree is made of 41,000 bulbs, 2,000 light channels, 2kms of cable & 200 hours to set up and that's it! It's all LED and for most of the 3 hours/night, less than 50% of the lights are running at any time but frankly, the video doesn't do it justice, you have to see it live!
