near the end of glitch, TS released craftybot! he automated some of the crafting tasks, taking the materials either from where you had conveniently left them out for him, or from your storage display boxes.
you could also run him from your inventory, but that meant you had to be holding all the ingredients and tools and he took up an inventory slot himself.
he was massively flexible, but seriously buggy. they went ahead and released him buggy because it was the last days of the game and they wanted us to be able to play with him.
here is some video of crafty making potions in my house.
