"Since I collect these randomly, here and there, I don't remember where I got most of them by the time I set to put them up here. This week, however, I do remember that createdigitalmotion.com hosts the 3-D picture below. I haven't been able to test if it works (since I still don't know where to go to buy those old-style blue/red 3-D specs), but I can almost guarantee you that it will give you a splitting headache if you stare at it for too long ;)"
