Today I have been thinking about the visual part, doing some sketches and all that. I'm not going to put any of them here, for obvious reasons. Although probably the end result won't match with any of these early drafts, but you would probably comment about them and that would influence me, which I don't want to happen.
I also thought a bit more about the way the components are going to interact together, which is something that I hadn't thought about in depth yet.
Apart from that, I haven't written a single line of demo code today :P
