Similar to shadertoy, but limited to a vertex shader and simplifies the code's interface with that assumption.

Cleary inspired by glslsandbox.com this one only lets you edit a vertex shader. The vertex shaders main input is just a vertexId that counts vertices.

Because limits are AWESOME! Like 4k demos (or 1k) setting limits almost always leads to more creativity.
