A toadstool, the Universe, King Midas, the Golem. This is not a free association exercise, but rather a list of concoctions my coworkers and I have produced in Infinite Craft, a deceptively simple browser game by developer Neal Agarwal, who you may know for creating a delightfully "unhinged browser game about passwords" last year.
Infinite Craft resembles earlier combination games like Little Alchemy or Doodle God, asking you to drag to combine two elements together on a big whiteboard in order to unlock new, ever more complex materials to work with. Like those earlier games, it starts out pretty bare, with your craftables limited to the four classical elements of fire, earth, air, and water, represented here by little flash cards with emojis.
