* I hacked around Submachine a little, and programmed the portal in Sub4 to
  act as a room teleporter. It now teleports you to a specific room, rather
  than a specific coordinate.

* I watched the first video Tom 7 made on Learnfun Playfun:

  I also read the first couple sections of that paper; those introduced the
  concept of the project and its purpose, and explained how the learning-part
  of the project works.
