IQ’s blog is very well known for the Shadertoy’s users, but it is also interesting to look of the page of this associate in the creation of Shadertoy. Pol Jeremias Vila
Shadertoy has been designed from the origin as a social media that enables graphics enthusiasts to create and share computer graphics knowledge.
Mainly the spirit of Shadertoy is closely related to the demoscene. Looking at Wikipedia you will have a good explanation of what it is.
