I think the fake USB aquarium is designed to be ON only when the computer is
on, in other words its only on when someone is 'working' at their desk.

WOW, you really cling to the obsolete technology! Filament Lamps! AA
batteries, and alkaline too no doubt... Its all Lithium power cells and
Xenon or LED bulbs these days ;) I bet you're still using some version
of Edisons carbon filament incandescent bulbs in your home too, even though
compact fluorescents cost less than $2, last 10 - 15 times longer than your
60 cent incandescent bulbs, and use 1/4 the electricity (soon to be obsolete,
though, when the cold cathode bulbs start appearing in higher wattages).
