No plans to build any of them... yet. I will build when I land on something that seems worth building. Once in a while maybe I get lucky and someone else will build one, which takes me off the hook (for a little while anyway).  I should clarify. I just find designing to be enjoyable. I have *way* more ideas (only a few of which are good, but Sturgeon's law applies) than I have time to build, so spewing ideas into a thread like this is a way for me to keep the juices flowing.
