I must be losing my...

marbles.

I've just taken 22 pictures of this marble - on the run, on the floor, with flash, without flash, with macro mode, without macro mode, and all sorts of other settings on my new toy that I can now no longer remember. Only my increasing hunger for some dinner and the nagging feeling that I really ought to have better things to do on a Sunday evening have stopped my game.

Does it show that I have exams coming up that I ought to be revising for?!
