Ultra-Flash mini-cowbell

Here's a new concept Heliographic flasher from Fish Creek Spinners.



I expect this flash will signal predatory fish from far range and send the timid ones packing!

Here it is in the test tank, notice the pink/purple lightening-like light dancing on the glass walls.






It brought the neighbor kids from two houses down, over to see it.
