I saw this great gif of the Van Schooten Ellipse yesterday, which was new to me. Immediate response: I must make. Problem: I've had trouble with making linkages in the past. Had to cheat and program the equation instead of making them geometrically. Had some nice exchange about it with Steve Phelps (@giohio).

Looking  closer, I realized that this was Archimedes' Trammel... which also gave me a tussle. This time I faked it again - using a slider to switch among the relevant intersection points. I'll keep trying. The GeoGebra difficulty is making a point that has two restrictions instead of one defining characteristic.

At GeoGebraTube: download . Unfortunately, the mobile version jumbles up the intersection points. Sigh.

Ideas on the GeoGebra? There's a forum thread to share that!

Researching the problem a bit, I found a good post (of course) at Cut-the-Knot, and a forum at GeoGebra. Van Schooten was a Dutch mathematician primarily known for defending and promoting Descartes' innovations.
