Right, the turtle and Tkinter are GUI apps, but the OP said they connect with the -Y parameter for X11 forwarding, so it should open an X11 window on their << machines - this is standard behavior for ssh. And the OP said turtle was not found, not that a screen couldn't be opened.

Thanx, Vern, you are exactly correct. My students have run several GUI apps, for example using java, via X11 forwarding in this manner.
I tried sample python turtle code I found on the web and got an import error. I was logged in directly on the server.
