Making-Of Sea Shell Sand Clock

The year is coming to an end, the Holiday season is approaching. In case you are looking for a nice present: I have completed my version of a sand clock: a clock writing the time into sand. The idea is based on the famous ‘Plotclock’ by the Fab Lab Nürnberg (https://wiki.fablab-nuernberg.de/w/Ding:Plotclock). That Plotclock is using a whiteboard marker to write the time and erases it with a wiper ever minute: very cool idea!”
