I'd have preferred an article about entropy sources in general.

The CF lava lamp is a cool curiosity, but also a marketing gadget.

I'm afraid my perspective is skewed by personal experience, but I flagged this without clicking the link.

I'm also afraid this might violate HN guidelines, sp I'll unflag it now and leave it at that.

But the regurgitation of older, well-received topics in pursuit of publicity is something I heartily detest.

So, I'm gonna skim for new details and stay quiet for now :)
