Mediums?

We had an English assignment in which we had to write a poem that had a lot of very strict rules. It wasn't a specific form, they were just arbitrary regulations. It had to be twenty-four lines long, and each line had to have some specific things - for example, line one had to have a noun, a number, and a colour. So I went to work on this, talked about a guy named Pauline playing a bass solo. When I had ten lines left, I thought, "Maybe I'll submit a bass solo with it!" I wrote the solo, then decided to just complete the assignment as usual, keeping the solo for something else. I was still interested in combining two media in one piece, though. I told the Cosmic Cop about it, and asked if she'd be instristed in cola-BO-rating on something. She agreed. Now, I've been working on some music for three days, and am going quite fast. When it's done, I'll record it and submit a cassette to the Cosmic Conundrum and she'll illustrate it. And it just might be the greatest piece of art of all time!
