are wooden gliders worthwhile building ?

serious question.
in this day and age where the slippery glass reigns supreme are there
any wooden gliders actually worth building ?

if your son was on the way to a glider instructors rating, as mine is,
is there a wooden glider design that would be worth building ?
something with reasonable performance that would be a sheer pleasure
to fly.

something a dad could spring on the kid.
