LOGO-L> Publication problems (help wanted)

[KERRB@Magill.UniSA.edu.au]

I mentioned before that I have written an article about animated fractals for 
the Australian Maths Teacher. (I'll publish a website version shortly and post 
URL here).

The editor of the computer section has asked me some technical questions that I 
am unsure of (one about Windows screen resolution and one about creating 
animated fractals on the macintosh). Can anyone help?

First problem: Screen resolution (transferring to colour print):

My only comment:
Is the Windows resolution 640x480 pixels (my current setting). How does this 
translate to dots per inch?
Can anyone help?

Second problem: Making animated fractals on the Mac

Have Mac users on this list been making animated fractals? 
If so, how have they been doing it?
(he wants to add a piece about how mac users can make animated fractals?)

Help on either problem much appreciated.
