Stereoscopic Tunnel Effect by Mindlapse, for the Hasbro My3D stereoscope, google cardboard, or any other similar stereoscopic iphone attachement.
You can enjoy the simple mono version of the effect in two variants, the simple texture mapped tunnel and the normal mapped (bumpy) with glowing messages version.
But if you have the Hasbro My3D, google cardboard, or any other stereoscopic viewer for mobile phones, flip the stereo switch, to experience the tunnels depth in glorious stereoscopic 3D.
