Want to engage, but brain is moving too slow for code

A couple of nights this week, I've been rewriting my photo app so it can accommodate regular photos as well as DeepZoom images or whatever else I come up with. Lots of abstracting interfaces and refactoring. I know that it shouldn't be hard, and I feel like I'm on a pretty good track now, but my brain is just unwilling to match my enthusiasm.

But it's getting there. Last night I cranked out creating albums and subalbums, navigation, uploading a single photo and displaying it. The tricky part is the counting of images of various types even though they live in the same album.
