Turtle graphics package wanted

[taurus!atlas!erickson@lll-winken.llnl.gov (David Erickson)]

I would like to be able to assign projects to second quarter CS students
that involve limited graphics output capabilities, something on the
level of sprites.  An example assignment would be to animate sort routines
on linked lists, or a simple board game.  Are there any public domain
graphics packages which are compatible with Sparc Verdix Ada or Meridian
Ada?

Thanks for your help.
