How about a giraffe with a collapsable drive shaft instead of a chain?

I guess we've gone off on somewhat of a tangent! But your idea about a
spring mechanism may have applications to the geared giraffe idea I'm
working on, as well. You're a veritable fount of ideas, Julian!

< but will you lose control with the chain loose when it is compressed?

I do think that more that a tiny amount of slack in a chain is
unworkable, if only because the chain would tend to come off. I take
it from Jack Halpern's recent writings that it's possible to ride
with 1.5 or 2.5 wheels, the odd half being composed of "slack", but
that's just beyond practicality for most of us mortals, don't you
think?

Anyway, my head is buzzing with ideas, gotta go. Thanks!
