I have visited my displays. Although I can usually spot an enclosure, I do not really see them and I am part of the decorating crowd. I do not believe that the regular non tech viewing public even notice them. They are much to busy following the dancing lights and seeing along with the music. Don't add extra work that is not needed. Also having read many lighting enthusiasts forums over the last couple years I don't recall that theft is a major issue for controllers. The bigger theft problem is display elements, like inflatables, blowmolds, lights. etc. Of damage to display elements by vandals (not thieves). If someone stole a controller how would they use it and where would they go to find out how to use it. Too easy to trace so therefore no value. I do put my name inside the case underneath the board where it can not be seen except by taking it apart. The only thing I ever had go missing was a wire frame deer that "wandered away from the herd". Not to say that it can't happen or has not happened, but it is rare. Unless I was in a neighborhood with a rep for having things stolen, I would not worry about theft. And with controllers in cases weather is not normally an issue. btw, I use metal garden stakes to hang my controllers on they do not split when pounded in. Just my 2 cents.
