I was experimenting today with GeoGebra 3D, trying to see how I could simulate a "ripple tank". The Geogebra part is not too bad (so far), but getting the 3D file embedded in a web page is a nightmare. Getting browsers, devices, operating systems,. and GeoGebra to get all in sync is not nice.
At any rate, I took a rather large automated gif copy of part of a file, doctored it up to shrink it down in size a bit, and put it here.
For its parent file, you will have to wait. It is still in "production."
