I caught wind of this from a great 99 PI episode that you can find here. Chindogu is the art of creating things that are not entirely unuseless. From the website:

chains of usefulness.
They represent freedom of thought and action:
The freedom to challenge the suffocating historical dominance of conservative
The freedom to be (almost) useless.
Highly encourage design interested folks to check this out.
