I put this on Instagram a while back and it just tickled me. What I did was to put my Pebble watch on top of my Twine box. The Twine is set to notify my iPhone every time it’s moved, measured by vibration. However, whenever the Pebble Time gets a notification it vibrates. So, once the Pebble Time is sitting on top of the Twine Box all it needs to do is to receive a notification from my iPhone and then a chain of events is triggered. The Pebble Time vibrates. This causes the Twine to notify my iPhone of a movements (via IFTTT). The iPhone gets the notification, it’s passed on to the Pebble Time, and so the cycle repeats.
I found it quite funny, but I guess no one else will.
