Long Exposure Fiber Optic Light Toy
A figure-8 design using the slow fade multi-colored mode.
This is my favorite of them all.
The toy I used is something my son got when he went to see the Walking with Dinosaurs show here in Baltimore. The toy is a dinosaur head with a red, blue and green light inside it. The head is placed on a wand and has fiber optic strands coming out the top. It also has a plethora of color modes in which they flash and blend into each other.
