Logo was first with turtle graphics but they are available
in most languages now. Certainly Turbo Pascal, Smalltalk, 
C++, Lisp etc all have turtle modules. Python does too but 
I couldn't get it to work - can't recall what the problem was.

Incidentally Logo is a list processing language rather like 
Lisp but with fewer parentheses. Modern versions have full 
OO facilities and you can even write windows programs if 
you really want! Worth a look for the language curious :-)
