Check out GeoGebra OER community. There will be a US conference this year, and the online resources and groups are good, too.
A lot of my students appreciate geometry through the following lenses: - Origami - Computer graphics, especially programming cool visuals for games - Escher, Dali, and other "surreal" space transformations - we are doing a lot of it in our "Alice in Wonderland" class, hehe. We watch videos a lot, too.
