Currently, I am waiting for inspiration to strike. Sure, I am polishing up some other projects, slowly extending them. You know the drill -- better commentary, testing for more unusual conditions, making the "pipeline" reach further in both directions, that kind of thing. However, I have a Difficult Problem that will require something special to get me going. The last time I was faced with a similar issue (some rather geometric issues, given that it is GIS), I kicked it around for months. One night I was ill and had to take my usual medications for it, and as I became very sleepy, the solutions began to appear to me as well-illustrated diagrams in different colors, with drafting-style callouts and such, a long parade of what I had been looking for. When I woke up, I drew them out and after then, I could begin to code. Everything else I am doing is basically pick and shovel work of coding. For this, though, I await the call from my muse.
