If you spend too long in the snow you get snow blindness; working on the same premise I can imagine you would get red LEGO brick blindness after making some of these massive festive Santas.
Found entirely on BrickShelf, this herd of Santas is more than enough to get anyone into the festive spirit. They are primarily found at the entrances of toy shops to induce a "WOW!" factor and kick-start the shopping mood.
If I was a child I imagine I would be totally blown away by these.
