Ink Jet for Lawns

This addition to a growing family of "lawn train" attachments can easily finish off your lawn after precision cutting and shining it. The main bed of the unit consists of several tanks of your choice of non-toxic inks. An ink jet is fitted just off the rear, as well as in the front. The front jet can apply a thicker coating for a background "canvas". The rear jet would do the detail work. I see this as primarily a color enhancement tool for the adventureous lawn tender. Messages are best applied for the benefit of passing aircraft (like "your wife wants you to pick up some milk," or "quit looking down and fly your plane," or maybe a simple "how's the weather up there?"). Your color scheme or message is keyed in and uploaded to its computer in advance. A powerful translation program is included, so that you may communicate in different languages. Naturally, spell check is included, since it is hard to correct errors written so big. A fragrance could be applied, as well. Infused vinegar, when combined with previously dispersed canola oil, could give one's lawn the smell of a nice salad. Or a designer fragrance could be used, such as the smell of freshly cut grass.
