Tardis, Now with Ambient Occlusion

Thought I should throw some Ambient Occlusion its way, because it makes such a huge difference. I also modified the way the geometry is created, it's just one corner of the Tardis now, mirrored around the X and Z axis with abs(). This allowed me to use less objects, allowing me to use more objects! So now all of the windows have the panes on them, and I added some of the little bars around the roof light. I'm thinking the next step is to improve the time vortex, describing it as "basic" is being needlessly polite. Here's the link.

Another Dr Who Themed Shader Experiment

Here's 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.

Shadertoy's Dalek was Lonely

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.
