Some scripts:

• simply swaps negative and positive prompts for giggles. Best with complicated prompts - but don't blame me for the horror show

• more advanced script that swaps negative and positive tokens depending on Mr. negativity rage

• requires both positive and negative prompts. As you move the optimism slider Mr. positivity will start dropping words from the positive prompt and repllacing them with words from the negative prompt. So you can use the negative prompt for things you want to mix into the positive prompt - sometimes but not always

Tip: add two very unrelated prompts to positive and negative box, set slider to 50, Check Clear negative prompt - and you get a recipe for random surrealism.
