I was at school with the CTO of GeoGebra in the 80s. He released his first geometry app in the early 90s, but I don't know if the current product owes anything to his early software.

Not really, it was in (very bad) C++ and GeoGebra is in Java. A couple of good ideas made it across (and hopefully none of the mistakes :)
