Outline 2 HTML Export Plugin
A “Semantic HTML” export plugin for OmniOutliner which can translate a simple outline like this:

into valid, well-formed HTML like this:

For someone who considers XSL to be child’s play, this should be no problem. And I, for one, would pay upwards of $20 for this plugin.
License Plate PSAs
You could use your license plate to help forward a political or social agenda that you feel strongly about, or even just remind people to do some good works. Examples:

E-snail-mail
Admittedly, it needs a catchier name, but here’s how it works:
The service provider has a deal with the postal service to intercept your physical (“snail”) mail before it reaches your home. You can choose to have different types of mail intercepted.
- mail addressed to someone other than your preferred name(s)
- bills
- advertisements
- mail from people on a custom address book
- etc.
You can get individual or compiled e-mail updates about your incoming mail that includes a brief description of what arrived:
- sender
- keywords and/or summary
- whether it requires a timely response
- etc.
The service will also keep digitized images of each page of each letter, just in case you need a printed copy.
Eventually, snail mail spammers will just start sending the digital images of their crappy advertisements to your address, if they know you’ve signed up for the intercept service, and we’ll be able to save a lot of trees and avoid a lot of annoying trash.
Short film: "Sam Raimi Does the Dishes"
A quick vignette (sixty seconds or less) in which Sam Raimi washes, scrubs, rinses, dries and arranges a load of dishes, up to and including the moment when the dishwasher door is closed and the knobs are turned, ending with the classic line, “Groovy.”
Watch the clips from Evil Dead 2 and Army of Darkness for inspiration.
Poetry format generator
Accept normal prose as input and reformat with an algorithm that splits up the lines by generating a random number from 1 to 7 and using that as the limit for the number of words on a line, so that you end up with poems that read like this:
Don’t fill up on bread
I say absent-mindedly
The servings here are huge
My son, whose hair may be
receding a bit, says
Did you really just
say that to me?
What he doesn’t know
is that when we’re walking
together, when we get
to the curb
I sometimes start to reach
for his hand
Sentimental Moment or Why Did the Baguette Cross the Road? by Robert Hershon
Also, consider automatically removing punctuation.
Microformat for Song Lyrics
A microformat for marking up the individual lines of song lyrics, so that searching and comparing differences is made easier.
It could use nested microformats like hCard for linking to the artist(s) in question.
Calvin peeing on "Copyright Infringement"
A car window cling or bumper sticker depicting Calvin peeing on the words “Copyright Infringement,” as a way of backlashing against the nearly innumerable and often stupid ways in which Calvin’s image is currently used to trash things like Dodge automobiles and commemorate dead soldiers.
Concept album based on the Tarot
Could be original music, could be a compilation, but it’s a guaranteed way of arranging twenty-two interesting tracks, in order of the major arcana.
