SentiSocial is a Twitter based trend analysis application. It collects data on topics that are trending on Twitter and exposes that data via a public API. Some of the data collected includes:

  • Average sentiment of tweets related to the trend
  • Popular tweets related to the trend
  • News articles related to the trend
  • Keywords found in tweets related to the trend
  • Countries in which the trend is trending
  • Amount of time the trend has been trending
  • Volume of tweets related to the trend

The web based SentiSocial frontend then queries the backend for the collected data and displays it in a readable and intuitive format.

Open Flood is a free and open source flood-fill puzzle game for Android. The goal of the game is to fill the entire board with a single colour in less than the maximum number of allowed moves. The size of the board as well as number of colours can be customized to change the game's difficulty. Boards can also be generated from seeds, allowing players to share challenging or interesting boards with others.
