Cat's Eye Technologies provides an implementation of Etcha written in
the Java[TM] programming language. This implementation attempts to
pen up/down semantics, but it is the Controller that implements the rule
that `>>>>` toggles the pen position.
+Cat's Eye Technologies' ridiculously over-engineering implementation of
+Etcha is in the public domain.
