I have been thinking of doing a Minecraft post but it requires effort as I would need to do a video to show off @gorc's redstone machines so it's one of the things that will probably never make it high enough up my todo list to actually get done XD
There's only so much help you can give people, after that they actually have to do things themselves and you gotta free yourself up to do your own things XD
baaaaah i hope you get to do it someday! i'd like to see :D
and yep. can only show the door, they gotta walk thru it, as they say~
