I thought this big American flag was pretty cool in the Harley Davidson Cafe on the Vegas strip. It's made up of hundreds of chains suspended from the ceiling, each one painted so that when it hangs it has the right colors in the right place. Then the stars are poking through with little lights that flash. And those bikes move along a conveyor so that different ones are displayed at different times. At least that was the idea, I didn't actually see it move while I was there.
I couldn't tell from up in the balcony if this was real metal chain or plastic. I tend to think it's plastic due to the weight issue, but if you can suspend full-sized Fatboys from the ceiling, then a few hundred logging chains may not be a big deal.
