The message can only be seen when highlighted (selected). Every post on my blog has invisible writing. Since Google's spiders don't realize the text is "invisible", it's a simple way to include search terms without confusing readers.

(Home tinkerers can flush and fill their own.) And further ideas: 2. several-color invisible ink cartridges, so a page can be printed in one pass, that can show totally different messages depending on the make-it-visible reagent you use later. 3. art-show animation using this technology. And 4. recycling, using the same paper several times by this process, an invisible palimpsest. It probably wouldn't smell very good, but offices often smell bad anyway, with all the personal care chemicals in the air and carpets and etc. Okay, there's the million-dollar idea: 1. invisible ink inkjet printer cartridges.
