Flow Indicators

[immo]

So, I was watching a youtube video from VCA, and in the background, it looked like they had these little paddle wheels mounted in a tank with their RFG (I'm assuming to demonstrate it's random flow). Did a quick google search, couldn't find anything. I really haven't seen anything that helps people get a visualization of the flow in their tanks. Other than throwing something like AB+ in there to see what it does. Does anyone know of any kind of "flow indicator"? I have a 3D printer, and can do some modeling, and most likely I could replicate what I seen in the video, and possibly even improve on it. Would something like that interest people?

You mean something like this but open for aquarium use?

That you could moove anywhere and act like a wind turbine so you can see direction and speed of flow into the tank. Im surprised i never seen that so far

I like the idea -- never seen one either.
I've been trying different lengths of dental floss tied to stainless steel straw for assessing flow but it's pretty LAME.

Yes.
