I know that mercury is used to make fluorescent lamps. Do you think "Mercury, Now There's A Bright Idea!!!" sounds ok....
Mercury is the Roman name for the Greek god Hermes, who was the messenger of the gods and the patron of commerce and gain. How about something connected to that?
Another possibility: the adjective "mercurial" has this definition:
characterized by rapid and unpredictable changeableness of mood
So how about something like Mercury--you never know what to expect???????
Mercury, a dense heavy liquid, was once known as "quicksilver," since it's shiny surface looked exactly like a clean specimen of silver ("static" silver.) But unlike silver, mercury's poisonous! So how about Mercury: Quick & Deadly!
Shiny, still myetrious!
