What Could I Paint For My Abstract Project In Art?

I have no idea what to do. I'm supposed to plan it tonight and have it ready by tomorrow. What we're doing is painting something abstract. It can be anything. From pure abstract (like scribbles and lots of colors, emotions, etc) to taking and object and making it abstract (where you take from the object and make it unique). I seriously have no idea. I have little ideas, but I'm not sure. Oh, and I decided to use acrylic paint and when it dries, chalk pastels. Thank you!
