I've currently got a fort running, one I've been saving the progress of each year on the map archive:
http://mkv25.net/dfma/usermaps.php?fortressName=Routpainted The idea is simple, create a pod like structure supported only by a support on the bottom, then at the right time pulling the lever. I aim to maximise the damage, so that means the more dwarfs, structures, and fancy stuff inside the Pod the better.
In my first year I realised my initial Pod would only hold about 30 dwarfs, so in year two I built a second, much large Pod. The first pod had farms and food related stuff in it, as well as the trade depot, and would be one day turned into a barracks.
The constructions of the second pod allowed me to hold over 100 dwarfs, as well as house nobles in detailed but small rooms. Then realising I had no burial area I built another smaller pod for burial.
The ultimate objects are two fold:
1) Construct a large structure that can be collapsed at a flick of a switch,
2) Attempt to collapse the structure ater surrounding it with water.
I explain my plan to flood an area so massive on the maps notes, plus other areas of interest.
Every game year I'll be uploading the latest map and adding notes of what I've done so far. Once its ready to explode I plan to record it as well, so if my PC does explode it should make for a good video. I think what will happen is all the internal floors will collapse and fall through anything not supported by a wall, which might result in a rather night concertina effect. Also the Burial Pod will have a massive drop beneath it so we'll get to see what happens to a several stories high structure if you drop if several stories in this game.
