another ShaderToy, this time based off of the time coordinates as seen in Doctor Who (2005) S7E13 - "The Name of the Doctor". While the picture does justice to the line drawing algorithm I created for the task (I was offline at the time), to really appreciate it you need to see it moving. This one maintains a constant framerate on my Nexus5, so should work pretty well on WebGL devices with at least that much power.

So I decided I'd create this shader to keep him company. Then a nice chap called Andre told me I could use his awesome sound shader (sound shaders a black magic to me, which makes Andre's accomplishment all the more impressive) as background music. Took me about 5 hours of effort, which included "figuring out how this raymarching biz works". The lighting is a bit off but I figure light is supposed to be funny in the time vortex. Also I'm not aware of a way to do ambient occlusion in a raymarching fragment shader.
