Got out these fluorescent Slinkies for some black light - but didn't get out the black lights yet. Here we have three intertwined Slinkies draped over black foam board. The camera is at an angle to make the image more dynamic.
This isn't as strong as my all time Slinky favorite - http://www.pbase.com/ed_k/image/94408294 - but I'll keep working at it for a few days and see if a new fav is in the works.
