Here are my complex solutions to the original puzzles. I was trying to get something as complex as bidaril, but it just didn't quite work out that way. Apparently you need a tricky puzzle to come up with a really, really, really complex solution that uses nearly every square in some way. For level 1 (abalone): cobizyl For level 2 (origami): cavikod. For extra funboredom, change the upward copier below the topmost dozer into an up-pipe. I ran out of time to do the others, sorry (waiting for the level 2 solution), so I will do them at a later time.
