Spell-it-out Lava Lamp

 Blobs? Curses!

I'm always fascinated by those lottery machines in which you open a tube, and a numbered ball shoots up. It's like magic, as far as I'm concerned. Of course, it's also bad for my wallet...

And I'm also madly in love with lava lamps. As, I think, we all are. And if you aren't, you should be, you sicko.

AND I'm fascinated with coming up with novel ways to swear at people.

So why not combine the three?

This Lava Lamp would have a shorter chamber than standard lamps to prevent too much heat loss. At the top of the chamber would be a set of 17-segment displays (like 16-segment displays, but with the addition of a dot at the bottom for punctuation). Rather than LEDs, these would basically consist of hinged flaps, which can create all 26 letters, numbers 0-9, and basic punctuation (! ? .)

By entering data into a keypad, these hinged flaps would open, allowing heated lava to flow into the spaces through a tube in the bottom, spelling out characters as necessary.

To prevent clogs, the spelling mechanism would have a higher specific heat than the wax or matrix, allowing the wax to remain heated and eventually pour out as the lamp is turned off.

To change spelling while the lamp is still on, simply press a "Clean" button on the keypad or lamp body, which would reduce the power, and therefore heat, of the lamp several degrees for several minutes, allowing the wax to pour out of the (still warmer) spelling mechanism and back into the matrix.

For simplicity, this could simply use a standard USB keyboard.

EDIT: Thanks to [half] for the link explaining what the hell those displays are called.

Annotation:







       Unless I'm missing something, you could only read the letters from the top, which you can't do on a lava lamp. But I'm for anything involving lava lamps.

       I believe you could read them from the sides - it's all about the access. I think if the access ports are directly below the letters, or perhaps below and slightly behind, the letters will stay filled with goo. There may be some small amount of leakage, but that might even make it cooler.   

       I should perhaps clarify that the spelling apparatus would, in fact, be inside the jar, or be an extension of the jar, so that it is in communication with the fluid matrix.

       If you could get the flow rates consistent, you could spell words vertically by having a set of five valves at the bottom and a forced-circulation fluid return. It would be necessary to make the flow rates for all the columns consistent, but if that was done stuff could be written in blobs that would slowly 'scroll' upward.
