 # starfield
 
-A starfield simulation using python 3 and tkinter
+A colorized, readily re-sizable starfield simulation using Python 3 & Tkinter.

+If you would like to learn how to use Python to create such graphics, then [you might enjoy this free training](https://www.udemy.com/course/introduction-to-turtle-graphics).
+
+Also feel free to enjoy the free tutorial @[Soft9000.com](https://soft9000.com/PY3KTG/index.html).

+![Larger, colorized, stars:](https://github.com/Python3-Training/starfield/blob/master/stars.gif)
+
+p.s. If you would like to plack (play + hack -=> Kobayashi Maru?) a game then you might enjoy [StarTrek for Python](https://github.com/Python3-Training/startrek1971).
