The power dips and the lights hum. Switchmode power supplies have negative resistance. The piece of paper on which I wrote my last serious LJ post has reappeared on the floor; it was headed paper from Continental airlines. I wrote the one before that on the back of a sick-bag. The room is dominated by the largest domestic projector I have ever seen. It has a flight case, on which is balanced an Ikea table, upon which in turn are two reams of paper supporting the projector. It all looks highly unstable.
