Presentation Mode on Android?

So I have a pool party at my house tomorrow, and was planning on setting up my nexus 7 with Spotify for the music. I want to leave it out for anyone to use, but want to basically lock Spotify open, disabling the rest of the OS and apps (somehow giving a bunch of guys access to my grindr account at a pride week pool party seems like a recipe for disaster)

Is there any way to accomplish this?
