Was wondering if there is a developer that can recreate a data field?

I recently found out that the developer of one of my favorite data fields passed away. I recently upgraded from a 530 to a 540 and the field is not available for the 540. Was wondering if there is a developer that can recreate?

It probably did more, but I only need something simple.

In a single field,  it rotated the ascent, descent and difference.  The settings that i cared about were how often it changed,  and what fields it actually displayed.

Personally, I only used it in a 1/2 wide field, and rotated the ascent and difference every 3 or 4 seconds.

If i knew how to do it. I would. 

Thank you.
