Kinda silly, and probably nothing new, but I've been working on this off-and-on for a few months now, and finally put my nose to the grindstone, and this is what I've come up with:
There are still a few bugs to work out. Some that I mentioned in that post have already been worked out, but the following post is also relevant.
No it's not silly. I like odd projects like this.
Tape, glue or rivet a bunch of coils to a piece of plastic, make them in a 'seven segment' dot pattern. Have the plastic with the coils on the back drop down into some ferrite power (laser printers have it) and when it comes up it displays the time. ;)
Then it lays back down, turns off the coils, turns them back on with the new time and raises again.

Of course I have a 120v fire alarm bell, a solid state relay and an arduino. I'll wake up Nixon! I've already pissed off the drunks on a Saturday with my testing. Opps.
