Human: There's this blank wall on my neighbor's house and I'm thinking of doing something to it.

Assistant: Oh, what do you think you'll do?

Human: Maybe spraypaint it.

Assistant: Do you have some special design in mind?

Human: I don't. Do you have suggestions?

I don't know...  There are many forms of creative expression, you might think of something.  What are you thinking of as far as the medium?
Can you describe some options you'd like to try?
