It would be nice if we could get a wiki like book/site/section together that started to summarize these ideas along with drawings. There have been some very clever ideas here over the years and it is very difficult to find them and put them to use.
Histories of what has worked, how long, where it failed, when it failed could avoid a great deal of duplicated effort.
The original ideas seem to work until they don't. I do miss the Dans' reports of spectacular failures, the evenings of song, etc.
Then again, perhaps after the basic idea, more is not better just more.
