Here we show how to generate new families of antiprismatic spherical tilings using GeoGebra, a well known free software commonly used as a tool to teach and learn mathematics. Within the described propose some spherical geometry capabilities of GeoGebra had to be extended. The outline of the algorithms behind some of the newly designed and implemented GeoGebra tools and applications will be given. Keywords: Spherical geometry, spherical tilings, GeoGebra.
