Komag suggested these ideas be posted here, so here they be.
Hang a daemon_head and a wall_button on the same wall, the button will be hidden "behind" at the same location as the nose. Walla, you now have a Daemon Head "nose" button to open doors, spring traps, etc.
Place a sign or scroll next to it that says "DON"T TOUCH MY NOSE!" and lay a trap for when they suscumb to the tempation.
Also, a wierd thing you can do with eye_sockets: Place one in the middle of a room, by either moving it off a wall using the arrow keys or adding a space on the other side, and add an item to the socket, and the item will appear suspended in mid-air from any angle. It can be plucked out - the only downside is only from one side.
This will only continue to work if the Editor allows you to move wall objects off the wall, so please don't change it!
