You just need a static png file for each number. name them 1.png, 2.png... etc.
I nicked Qosimo's pngs from the qbw flipclock thread and resized them to 25 X 36.


Create a folder in home/opt/maemo/usr/lib/advanced-clock-plugin/digits. Name the folder whatever you like.


In the advanced clock plugin settings select;
- use images for drawing digits
and select the image set you created.


Thanks again to Wonko, qosimo, etc...
