Perforated/"Expanded" Patterns. DWG/DXFs

Hi, do any of you have any good perforated or "expanded" looking designs? I found a few good ones, but looking for more.

http://accurateperforating.com/patterns <----- The ornamental section has some pretty neat patterns.

 

You can generate your own patterns...

Generate your shape.
Select it.
LAYOUT/ARRAY
GRID
Enter parameters
Add totals.

Done.

 

Right...just wondering if anybody had any designs they wanted to share.

 

Thank you for the information though.
