Frog whirligig(please note this is an untested pattern and may not work as planned)
The pattern has an optional Lily pad weathervane. The actual positioning of the frog and fly have not been determined. The place to put the frog and fly would have to be tested in the wind as the tongue propeller may act as a weathervane lilly pad may not be needed.
I have also contemplated using a small electric motor in the mouth and then attach propeller to motor. This would act as a generator which you could run wire from there to the fly. Using an LED for the fly's body making him light up at night. So I guess that would make him a firefly.
