I'm not a fan of towers =/ They get kinda boring after a while.

Done. I would post some, but it doesn't look as impressive without video.
Mostly secret entrances. Hidden behind bookshelves is my favorite, but I made some that create a staircase going into the ground (ground pulls away to make steps, not actual staircase blocks). Others are simple traps, farm equipment, that kinda stuff. Had my fair share of redstone creations.
