Abstract Thursday - Liquid, soon

Such a windy day today, it's been a good day to today the shelves in my study. 

In fact I can now see that I have shelves... There's a thing, called "book accumulation syndrome" and we've both had it for years. Something has to give, and in my case it's a decade or so of magazines on various themes. And a quantity of dust.

Some of the dust can be seen in my experimental work, "almost liquid". iPads do get quite hot after a while.
