When it's too cold and dark to venture outside, I bring the clouds in to me... And then take photos.
The above image features cotton ball clouds. I have seen various photographers experiment with indoor clouds, and I think the result often looks amazing. Rosie Hardy's stuff is particularly inspiring (below). Also, have a browse through my Flickr favourites because there are other cute cloud photos there.
I'm a bit bored with taking photos in my room. Tomorrow I'm going to brace the chilly weather and take some outdoor photos. I may post them here tomorrow if they are share-worthy.
