Ari Wilson's code, including a variety of projects:

KeeStand is a cloud password manager like LastPass.

BlockFort is a web-based game similar to Minecraft but with less gameplay and more world-building :). Saves are backed up to the cloud.

PebbleScores records high scores for Pebble watch games. I use it in my Falldown game.

Interesaint is a web-based RSS/Atom feed aggregator designed for high volume feeds. It learns and surfaces the items of most interest to you.

Scrabblish is a Scrabble solver. It is also available in command-line form here.

Seismo is an Android application that measures the strength of vibration, shaking, and movement around you, much like a real seismograph. Seismo Wallpaper is a live wallpaper adaptation of Seismo.

Design docs for these projects are stored here.
