I would like to think an app I made ages ago might be decent for a few minutes (perhaps longer if you muted the volume and played your own music on a separate device?).
I basically made it because there was literally no psychedelic content for Cardboard at the time. :D
It's called Strike the Colour
EDIT: Oh also, if you haven't tried Julius Horsthuis' 360° fractal videos, I highly highly recommend you download those and check them out. My favourite by far is From Nothing, which is also in 3D.
Looks like a way better version of an app I made for Cardboard ages and ages ago. Nice work! :D
Would love to check out an alpha build in the Rift - hard to say what should be different when watching on a screen... ;)
Strike the Colour VR on the Play store
It shouldn't be...
