I haven't been working directly on the layout lately; it's summer and we got busy w/ graduation season around our house (one from high school, one from middle, one from grade school, and a birthday - all within two weeks!).
However, I have been finishing up a model of the USS Enterprise-D, which my oldest son gave me a gift quite a few years ago, and which I thought I should probably finish up before he leaves for college (alarmingly soon, now...). It's got fiber-optic lighting, and to properly paint it has hundreds of tiny windows, panels, etc.
It's not my greatest achievement, but it's been great to re-discover some painting skills long dormant, and learn new skills I haven't used in building the layout. Perhaps I'll post a picture if it turns out ok.
