Ok, the critter enlarger has me sold already but I'm a complete sucker for that kind of thing.
The remote mail terminal is an interesting one and could actually be extremely useful and the rest seems kinda unimpressive. I guess I'll be feeding injectors to my alchs but I don't like the idea that mega mana pots are going to be even more irritating to make.
The tonk stuff seems like some kind of remote control toys. There's also a (presumably) small goblin zeppelin with a cannon on deck in the modelfiles, along with a steam"tonk" which looks like a pinkish steamtank like those outside IF. New Engineer pets?
