This fun and easy to make desk toy was inspired by the Hypnotoad
from the TV series Futurama
. The Marvelous LED HynoFrog
uses slow color changing LEDs to create a mesmerizing effect. The Marvelous LED HypnoFrog
employs a magnetic reed switch to turn it on and off: when the frog is placed on top of a magnet, the eyes will illuminate and start changing colors; when removed it will stop.
