There exists interesting interactive technical software (not just glorified flash cards). For instance I can remember playing some puzzle game about optics circa 2000, and another about mechanical devices. I’ve never heard of such software being used in a math class though. The one bit of very nice software that does get used some places is interactive constructive geometry tools like Geometer’s Sketchpad (1995), Geogebra, or the like, though we didn’t know about those in my high school geometry class (also circa 2000).
