This is where I will share or link to GeoGebra files. (See What to Bring)
Complex number games are here. (I accidentally skipped those in St Louis!)
Doctor Dimension files are here. (Note that we uncovered a mistake: in the fifth applet worksheet, part (a) cannot be done.)
Function diagram files are here.
The Perspective Lab simulation is here.
A construction unit for geometry (previewing "geometry of the parabola") is here.
