At The Cloud Appreciation Society we love clouds, we're not ashamed to say it and we've had enough of people moaning about them. Read our manifesto and see how we are fighting the banality of ‘blue-sky thinking’. If you agree with what we stand for, then join the society for a minimal postage and administration fee and receive your very own official membership certificate and badge.

A ovo je skroz cool - manifesto gore pomentuog kluba:

WE BELIEVE that clouds are unjustly maligned
and that life would be immeasurably poorer without them.

We think that they are Nature’s poetry,
and the most egalitarian of her displays, since
everyone can have a fantastic view of them.

We pledge to fight ‘blue-sky thinking’ wherever we find it.
Life would be dull if we had to look up at
cloudless monotony day after day.

We seek to remind people that clouds are expressions of the
atmosphere’s moods, and can be read like those of
a person’s countenance.

Clouds are so commonplace that their beauty is often overlooked.
They are for dreamers and their contemplation benefits the soul.
Indeed, all who consider the shapes they see in them will save
on psychoanalysis bills.

And so we say to all who'll listen:
Look up, marvel at the ephemeral beauty, and live life with your head in the clouds!
