Internal projects

  • Propose a project from another chair
  • Program a web-based, turn-based, two-player strategy

card game, using the Spring framework and db4o OODBMS

  • Example: something like Magic The Gathering card game

(www.magicthegathering.com), or a card game you like that still does not have an online version.
