Sometimes, you can increase adc_bailout to around 0.01. Depending on the 
scene, the effect can be imperciptible and speed things up noticably.
Toghether with a larger adc_bailout, you can increase max_trace_level. A 
value of 10 don't look like is't large enough.

Move your finish to the end of the blob so that it's applied once to the 
whole blob instead of to each individual components.

As this is a radiosity scene, your spiral is lighting it's surrounding. 
Be sure to set ambient 0 for everything else.

You use an extremely small threshold value for the blob. This can cause 
some artefacts. Try using a larger one and increase the radius 
acordingly. It will also give you smoother surface.
