Twelve Drummers Drumming was the keenly anticipated light to complete the sequence The Twelve Days of Christmas - here's the story of how the light was designed, built and animated and made its debut for Christmas 2010.

We're hoping to have a feature from all the teams involved in making this happen - Roy, the fabulous builder and designer of most of the lights; Gordon and the engineering side who animate the lights; the electrical team and the erection team..... but they are very busy planning this year's lights so it might take a little while to collect them all. So keep checking back.

We're hugely grateful to Gordon for providing the following information on the engineering challenge  - 'Bringing the Display to Life'....
