Some links
Sections in this page
Other sites or pages of mine
- fruitsq.com, about making circular objects (such as fruit) square. You will also find some galleries of my photos here.
- Our border terriers, Buddy and Kelso, both at about 14 months old.
- Nothing to do with imaging: Sudoku addicts might find my Sudoku helper page useful. A major difficulty with Sudoku is going back if you make a mistake. My page makes that easy. By using different colours you can highlight recent entries. You can also save the state at any time and go back by reloading it. I have also included a "Solve" button but that is only as a last resort. It does not necessarily solve the whole puzzle in one go.

- British Astronomical Association (BAA)
- The Computing Section of the BAA - a new site (March 2010) which I developed.
