Watch: Jaquet Droz: Bird Repeater Openwork Automata

Swiss company Jaquet Droz has been making watches since 1738! In their film you can see the 8 different movements of this exquisite timepiece: with a worm in the mouth, mechanical blue tits tend their young ones beside a flowing river. One parent nods their head and stretches their wings while the other lowers a caterpillar to the eager young ones and the egg hatches. Amazing.

Toad King

Toad King is a great android app to help you track things. Not just moods. Anything. The "Markers" are totally customisable. It's simple to use, displays simple graphs in bar or plot form, data is easily shared via gmail, cloud etc. The only drawback is that it does not aggregate the data of multiple markers into 1 graph. Great for nerds and control freaks.

Update Tuesday October 2nd, 2018: It looks like Toad King is not available on / has been removed from, Google Play, too bad!
