Shout out to empressplay and her teammate(s) (sister?) for their work on turtleSpaces, an underrated, solid implementation of 3D logo in golang that can run on the browser. I've used it to teach children, and they've quite liked how easy it is to create 3D games and animations that can be looked at from any angle. Thank you for creating turtleSpaces and for the endless work adding features, fixing bugs, releasing new versions and quickly answering questions! I've no connection to it other than being a grateful user.
