Well, not very proud of the current result really.
I rendered the scene with the HDR image off and a cylinderical 
lightsource over the blob. Saving the photon and radiosity data.

The caustics seemed to look okay.

Then I switched off the lightsource put the HDR image back on and upped 
the reflection of the floor to 0.5.

The result is attached.

:-(

The caustics are now transfomred to shadows... I'm now renderingwith a 
less reflective floor (0.1). But I'm afraid I'll loose the effect I was 
going for.
