DMT I

First of the series, Delineation of Moving Transience, with no ads. This ad-free app displays an artistic psychedelic animation fullscreen. Be prepared to be blown away by the psychedelicness of the animation! The animation is likely to wow! Use an HDMI cable to connect to your TV or projector.
=================
Note that this application is mildly GPU intensive, so you can always get a refund within two hours at the Google Play Store, for instance, if your have a fairly legacy or old phone that has less GPU power than most phones today.
