I have this picture in my head for a couple of weeks now: she has a stadium tour, every attender gets a glowing wristband with the ticket which' light is controlled. Under Pressure (since its lyrics' about love is amazing imo and it's a HUGE song with great live potential vocally and visually) would be the encore, and just like the krills in 
Happy Feet 2 the whole stadium would be glowing to the beat. P!nk would stand at the end of the catwalk, the lightwaves would start from her and run through the whole building. I'm sure it's hard to organize it but it would be really mesmerizing.
