caustics with blender and cycles

When I modeled some glass metaballs yesterday I found out that the blender-internal renderer doesn't support caustics (the light reflections on the ground, when light falls throug a sphere of glass for example).But after some googeling I noticed that this is the perferct oportunity to give the new blender renderer named cycles a try - because cycles renders them. After some experimenting with various lightsources I finally used two small planes with an light emmiting material.

It also took me a while to generate a material in the node editor that displays a gradient on the backgound, because relies on the node editor much stronger than the blender interal renderer and I haven't used material nodes so far.

Unfortunately my graphics card is too old for blender to use the GPU for rendering - so it took a while to render on my box

    I've been working on this issue myself for a new tutorial website I'm working on. I have a sort of solution for you that cuts down on time drastically. Take a look.
