What's your Favourite contraption?

Tell us about your favourite contraptions that you have put together on G-Mod, one of mine is my "Beast" its pretty much a bunch of machine guns on wheels (yeah i know classic been done before g-mod contraption). I used my "Beast" to mow down countless amounts of NPC's its good fun.
