Round in circles

I needed a compass to draw circles in different sizes for my Gingerbread Train and came across these in my searching. It took me right back to my school days - it came with a projector, triangle and small ruler. I wonder if they are still used today ..... 

The main event today was lunch with T's bookgroup in the Bridge Restaurant in town. I'd never eaten there before and was impressed - the food was very tasty (and filling).
