What online game am I thinking of?

I just had a memory of an online game I played years ago but cannot remember the name or full details. Here is is what I do remember:

It was a bunch of little pictures of things and you can combine them to make other things. For example, you could have a picture of fire and a rock and combine them to make a volcano and now you have a picture of a volcano you can add to stuff. Does anyone know what I am talking about? Thanks.

Infinite Craft?

Infinite Craft (neal.fun)

Doodle God?

Stacklands?

I remember that game! IIRC it was fun at first but eventually some of the combos were pretty obtuse.

I appreciate the guesses but I think I found it on my own. This site linked below is not the version I played years ago and I am pretty sure it has a different name (I think the original was just called Alchemy) but this is basically the same game:

Edit: I think Infinite craft above is a variation on the same game.
