LOL! I really like it...I want more haunted furniture. I do recall now, that I saw a glowing coffee table in a vacant house, and wondered to myself what item that was. xD
Enya Gaia is in Egypt right now, so I can't test the eyedropper thing, but I'll get back to you guys when I do.
Oh, I just had a thought...you know when you're in Buy or Build mode, and you mouse over a piece of furniture, and it glows to indicate that's what the cursor is touching? Maybe these pieces of furniture got 'stuck' like that somehow, via some rendering glitch.
