Looks pretty good for a first timer. I was actually trying to make a skin to go with a skin that I was making, but instead, this came out.
1. Open the Aston Setup proggy
2. Click on "Plug-Ins"
3. Select "Aston Clock" (You should have it)
4. Click on "Setup Plugin"
5. Click on the Files menu and "Load Settings"
6. Find the GreenLCD.apc file, and open it.
