Interesting: a chakra/charka* improvised from a cardboard box.

I still harbor vague fantasies of learning how to spin, despite not having time for another hobby and despite my few experiments with a drop spindle not going very well.

(*sources seem to disagree on how this should be spelt. I've seen "charka" in some serious fiber publications, but Craftzine blog uses "chakra," which is also the word for the "energy centers" some yogini believe in.)
