I agree - however I'm not sure that a dedicated visualisations generator will make it's way into MixEmergency just yet. There are a few of other ways to achieve generated visuals currently: You can use audio-reactive Quartz Compositions (there are a few basic ones included with MixEmergency) to do this. It may be a little complicated to create custom ones if you're not familiar with Quartz Composer though. We are looking into including more example compositions with MixEmergency - and it's even possible to convert some of the iTunes visualisers (such as Jellly, Lathe and Stix) to work within MixEmergency. I could e-mail you a few examples if you would like. Another option is to run a separate visualisation generation application, and then mix between MixEmergency and the other application using the new Background transitions.
