[HINTS] -To make a parameter respond to the microphone press any one of the buttons with a blue arrow on it. A controller window shows up, press mic and the parameter will now respond to the microphone. Gravilocity was inspired by gravilux, and gravitarium, not to mention all the other particle play apps out there. *****Totally Awesome.... Running on an iPad this is seriously psychedelic. I have tried every other visualiser on the iPad and apart from it's bigger brother I-beams this eats them all for breakfast. I have said it before but the author of this software is a real genius. - AAWh *****One of the best of it's type *****Its the best particle manipulator I've messed with. Really cool job Created by Gedalia Pasternak, a Computer Graphics Engineer whose work has been seen in television commercials, video games, and the occasional military training system.
