I like the old-timey bizarre mechanical linkages used to acheive the
weird motions folks used to really get excited over.

They're hardly "bizarr". I use such linkages on my machines to make
explosive materials. Those 'bizarre' linkages are really a basic part of
mechanics.

Look at some of the OLD (say, pre-1960s), purely-mechanical manuals on how
to achieve various motions -- it's all in there!

Here's a lovely tome into which one can get themself nicely lost:
