Pebble smartwatch app
For fun, I've implemented an animation of the sampling of Hamiltonian paths on a 6x6 square grid as performed by the backbite algorithm, as described on my Hamiltonian path page.
This implementation makes an update every two seconds, alternating between the two ends and showing the intermediate step being added.
If you have a Pebble smartwatch, you can install the app by downloading this recently compiled (February, 2016) version of the app. One of these days I'll make it available on the Pebble app store, if anyone seems to like it!
