Cool post over on Hack-A-Day about corn maze entrepreneur Scott Skelly, shown above with his trusty GPS-enabled riding lawn mower. Scott explains his maize-maze-making process thusly:

A maze starts as nothing more than a large field of corn. The design is created using a computer, then translated into GPS coordinates by fitting it into a field whose outline coordinates were previously captured on foot. Once the field coordinates are reconciled with the map design the data is used in one of two ways; the routes can be made by tilling under a path when the corn is very young, or more commonly it is cut lawn-mower-style when the corn is anywhere from knee-high to full grown. This corn-meets-satellite hack makes for a whole lot of fun!
