acme-tiny-rules allows you to create beautiful (but nonsensical) inference rules by drawing and erasing lines. Left-click to draw a line, right-click to erase. It is a parody of Tiny Glade, which allows you to create beautiful castles by drawing and erasing lines. Here is the part of the Tiny Glade trailer I was trying to emulate:

acme is the traditional prefix for joke packages in the Haskell ecosystem.

Someone posted the above Tiny Glades trailer, saying "this but for compilers, that's my goal". Presumably they meant that they want creating programming languages to be effortless, with the program fleshing out the rest of the compiler from a few user-given constraints. I wrote acme-tiny-rules as a joke response.

The joke, of course, is that acme-tiny-rules takes the analogy too literally. It borrows the aestetics of continuously completing user-drawn lines with something beautiful, or at least beautifully-typeset. But it doesn't deliver an iota of value, and thus doesn't actually build towards the dream of deriving compilers from constraints.
