<p>Be careful with your cameras, they can't be trusted to just take
a picture these days, who knows what post-processing you will get
this week. Given what cameras optimize for (what people can see
and like to see), lava lamps seem a better target than black, the
lava lamp gyrations seem likely to make it through to the other
side as entropy.</p>

<p>P.S. Iphones have a setting the discourages the camera from too
much tampering, I think it is named something about taking
pictures more quickly. Though who knows what it will be and what
it will do next week, and what <i>I</i> heard has to be at least
a week old by now.</p>
