CAD in wxPython

[jm.suresh]

Hi all,
I am trying to write a small program to view VLSI mask layouts.

I am trying to display polygons with different *transparent* patterns.
How can I do this in wxPython. Can you please give me some pointers if
some application has already done this.

Look at the images in these web pages. I am trying to create something
like this.

My dream is to develop a full fledged eda environment on top of python.
If you are also interested contact me.

Thanks.

regards,
Suresh
