Civil War scene by jpark4evr

From the user:

"The lighting kit inside the burning building is a custom lighting kit for Lego products, designed by Rob Hendrix (Brickmodder.net). Each kit has numerous functions programmed in them. I have mine set to a "flickering" effect for fire.

This was used in my large Civil War diorama, which can be found here: http://www.flickr.com/photos/29934333@N02/2800299917/in/set-721576083192...

It's a really nifty product for Lego fans that is certainly worth buying."
