Smoky.

I was playing about with smoke from an incense stick this afternoon, and I then spent some time faffing around with one of the images on the computer.

There is endless fascination in the patterns made by smoke;  it is a long time since I last tried these, but I am sure I will try it again quite soon.  Apart from anything else, I still have a lot of incense sticks left in the packet.

At least my study studio now smells very sweet (a wild berry scent called "Tranquillity").
