Welcome to my playroom

These pages have nothing to do with boules or Machen Pétanque Club. I just happen to have put them here to see if they work. However you found your way here, welcome again.

Many years ago I used to write interactive stuff for my students at what was then the University of Glamorgan. Now I've just done a short course with Futurelearn which has inspired me to re-look at what I did 15, 20 years ago.

These pages are my playroom but you too are welcome to play with my toys - not that there are many.

As a retirement hobby I started learning Spanish.
