Well, I’m still stuck on playing with caustics. Here is my latest.
nice, i like the variety of colors
is there also some DOF?
SamAdam: Thanks. Yes, there is a bit of DoF in that one, but I reworked it in this next one.
I worked with my alpha channel a bit for a better blur effect, as well as reworking the lighting a bit. The changes are subtle, but I think they’ve made a rather huge difference.
same problem as youre monkeys
nice job with the caustics 
the second one looks much better
SamAdam - Thanks.
@ner - How should I go about fixing it? An IcoSphere world? A world texture? A simple environment?
Looks good.
Remember this post?

Looks like it was worth it after all. 
JDA <— runs for cover. 
Heh - JDA, you have a point. My sentiments concerning YafRay have been changed with the release of Blender 2.34 and YafRay .07 - though I never did figure out what the website you pointed me to did. The new release doesn’t seem to have any problems with world textures.
