Wrist sundials: have sun-fun
When pupils were attending True Time Workshop (2009-2011), many of the discussed ideas were inspired by "what-can-be-found-in-internet".
Other ideas for implementation:
- All new mobiles have compass-level application, thus, alignement of such sundials is a very simple task nowdays.
- You can have changable dials for different occasions.
- A special braslet can be used for latitude adjustment.
